+Core Cooldown targets **WCAG 2.2 Level AAA** conformance - the highest level of the Web Content Accessibility Guidelines. A break timer for preventing repetitive strain injury should be usable by everyone, including those who already live with disabilities.
+
+> **Why AAA?** Most applications stop at AA. We went further because the people who benefit most from a break timer - those with repetitive strain injuries, chronic pain, or vision impairments - are the same people who need the strongest accessibility support. AAA isn't a checkbox. It's the right thing to do.
+
+#### Contrast & Visual Design
+
+| | Feature | Standard | Description |
+|:--|:--------|:---------|:------------|
+| 🎨 | **Enhanced text contrast** | AAA 7:1 | All body text meets 7:1 contrast ratio against dark backgrounds. Secondary text `#a8a8a8` on `#000` = 7.28:1. |
+| 🔤 | **Large text contrast** | AAA 4.5:1 | Headings and large text (18px+) meet 4.5:1 minimum. Timer countdown, break titles validated. |
+| 🎯 | **Non-text contrast** | AA 3:1 | UI components (toggles, steppers, rings, chart bars, color swatches) all meet 3:1 against adjacent colors. |
+| 🖥️ | **Windows High Contrast** | AAA | `forced-colors: active` maps all theme tokens to system colors. Full usability in all Windows contrast themes. |
+| 🐢 | **Reduced motion** | AAA | `prefers-reduced-motion` disables all CSS animations, JS Web Animations API effects, and momentum scroll. Zero functionality loss. |
+
+#### Keyboard & Navigation
+
+| | Feature | Standard | Description |
+|:--|:--------|:---------|:------------|
+| ⌨️ | **Full keyboard access** | AAA 2.1.3 | Every control operable via keyboard alone - no exceptions. Arrow keys for color pickers, steppers, radio groups. Tab/Shift+Tab cycles all interactive elements. |
+| 🔍 | **Visible focus indicators** | AAA 2.4.13 | 2px solid white outline with dark shadow fallback on every interactive element. No hidden or suppressed focus rings. |
+| ⏭️ | **Skip navigation** | AA 2.4.1 | Skip-to-content link bypasses the titlebar on Tab. |
+| 🏠 | **Focus management** | AA 2.4.3 | View transitions auto-focus the new view's heading. Break screen traps focus. Dropdown focus returns to trigger on close. |
+| 🏷️ | **Heading structure** | AAA 2.4.10 | Semantic `h1` > `h2` hierarchy across all views. Settings sections use `h2` with `aria-labelledby`. |
+
+#### Screen Readers & Assistive Technology
+
+| | Feature | Standard | Description |
+|:--|:--------|:---------|:------------|
+| 🗣️ | **Live regions** | AA 4.1.3 | `aria-live` announces timer state, breathing phase, break activities, status changes, and celebration events. |
+| 📊 | **Semantic roles** | AA 4.1.2 | `progressbar` on timer rings, `switch` on toggles, `tablist`/`tab`/`tabpanel` on stats view, `radiogroup`/`radio` on breathing patterns, `alertdialog` on overlays. |
+| 📋 | **Data tables** | A 1.3.1 | Screen-reader-only data tables behind the 7-day chart provide the same information non-visually. |
+| 🏷️ | **Accessible names** | AA 4.1.2 | Every toggle, stepper, button, swatch, and form control has a descriptive `aria-label` or visible label. Sound presets use `aria-pressed`. |
+| 📝 | **Page titles** | AAA 2.4.2 | Dynamic `document.title` updates per view ("Core Cooldown - Dashboard", "- Settings", etc.). |
+
+#### Target Sizes & Interaction
+
+| | Feature | Standard | Description |
+|:--|:--------|:---------|:------------|
+| 👆 | **44px touch targets** | AAA 2.5.8 | All interactive elements (buttons, toggles, steppers, color swatches, titlebar controls) have minimum 44x44px hit areas. Visual size may be smaller - the clickable area extends invisibly. |
+| 🎯 | **Celebration persistence** | - | Milestone/goal popups stay visible on hover or focus, with keyboard-accessible dismiss buttons and Escape key support. |
+| ⏱️ | **Hold-to-repeat** | - | Stepper +/- buttons support press-and-hold for continuous increment, with keyboard Enter/Space triggering the same behavior. |

+# WCAG 2.2 AAA Compliance Design
+
+**Date:** 2026-02-18
+**Scope:** `break-timer/` (frontend + CSS only, no Rust backend changes)
+**Goal:** Achieve WCAG 2.2 AAA conformance while preserving the existing dark-theme visual identity.
+
+## Audit Summary
+
+42 issues found (8 Critical, 14 Major, 20 Minor) across 28 source files. The app already has solid AA foundations: focus indicators, reduced motion support, forced colors mode, ARIA roles on custom widgets, screen-reader text, and keyboard support for complex components.
+
+## Design Decisions
+
+1. **Secondary text color:** `#8a8a8a` -> `#a8a8a8` (7.28:1 ratio, minimal visual change)
+2. **Target sizes:** Enlarge controls to 44px (visual + padding), including 20px traffic lights, 28px swatches, 36px steppers
+3. **Auto-dismiss toasts:** Persist until dismissed when user hovers/focuses; auto-fade only if untouched
+
+---
+
+## Section 1: Color & Contrast System
+
+### Theme Token Changes (`app.css`)
+
+| Token | Current | New | Ratio on #000 |
+|-------|---------|-----|---------------|
+| `--color-text-sec` | `#8a8a8a` | `#a8a8a8` | 7.28:1 |
+| `--color-text-dim` | `#3a3a3a` | `#5c5c5c` | 3.5:1 (decorative) |
+| `--color-border` | `#222222` | `#3a3a3a` | 2.63:1 (non-text) |
+| New: `--color-input-border` | — | `#444444` | 3.14:1 |
+| New: `--color-surface-lt` | — | `#1e1e1e` | 1.28:1 (bg-to-bg) |
+
+### Hardcoded Color Replacements
+
+- All `text-[#8a8a8a]` -> `text-text-sec` (Tailwind theme token)
+- All `border-[#222]` -> `border-border`
+- All `border-[#161616]` -> `border-[#333]` (card dividers: 3:1)
+- All `bg-[#141414]` (stepper bg) -> `bg-[#1a1a1a]` with `border border-[#3a3a3a]`
+- Toggle OFF knob: `#444` -> `#666`
+- Mini paused text: `#555` -> `#a8a8a8`
+- Placeholder text: `#2a2a2a` -> `#555` (3.37:1)
+- Danger color: `#f85149` -> `#ff6b6b` (7.41:1)
+
+### Focus Indicator Safety
+
+When accent color is too dark, add white outer shadow fallback:
+
+```css
+:focus-visible {
+  outline: 2px solid var(--color-accent);
+  outline-offset: 2px;
+  box-shadow: 0 0 0 4px rgba(255,255,255,0.3);
+}
+```
+
+---
+
+## Section 2: Target Size Enlargement
+
+| Component | Current | New Visual | Hit Area |
+|-----------|---------|-----------|----------|
+| Titlebar traffic lights | 15x15px | 20x20px | 44x44px (padding) |
+| Color swatches | 22x22px | 28x28px | 44px spacing |
+| Stepper +/- buttons | 28x28px | 36x36px | 44x44px (padding) |
+| Toggle switch | 48x24px | 52x28px | 52x44px (padding) |
+| Back button | 32x32px | 40x40px | 44x44px |
+| Stats tab buttons | ~60x30px | ~60x40px | 44px height |
+| Activity star/remove | 32x32px | 36x36px | 44x44px (padding) |
+| Time range buttons | 32x32px | 36x36px | 44x44px (padding) |
+
+Strategy: Use `min-h-[44px] min-w-[44px]` on interactive elements with padding for visual sizing.
+
+---
+
+## Section 3: Heading Hierarchy & Document Structure
+
+### Heading Fixes
+
+- Each view keeps `<h1 class="sr-only" tabindex="-1">`
+- Settings/Stats: Change all `<h3>` to `<h2>`
+- Working Hours section: Add missing heading
+- BreakScreen `<h2>` stays correct
+
+### Landmark Regions
+
+- Titlebar: Wrap in `<header role="banner">`
+- Dashboard bottom buttons: Wrap in `<nav aria-label="Main actions">`
+- Stats tab bar: `<nav>` with `role="tablist"` / `role="tab"` / `role="tabpanel"`
+- All sections: Add `aria-labelledby` pointing to heading `id`
+
+### Document Title
+
+Add `$effect` in `App.svelte` to set `document.title = "Core Cooldown - ${viewName}"` on view change.
+
+---
+
+## Section 4: Keyboard & Focus Fixes
+
+### C5: Strict Mode Keyboard Trap
+
+When `strict_mode` is true and buttons are hidden, render a visually hidden focusable `<span tabindex="0">` with sr-only text "Break in progress, please wait" so focus trap always has one element.
+
+### Stepper Keyboard Hold-to-Repeat
+
+Add `onkeydown` handler that starts repeat on held ArrowUp/ArrowDown/Enter/Space.
+
+### `pressable` Keyboard Feedback
+
+Add `keydown`/`keyup` listeners for Enter/Space to trigger same scale animation.
+
+### `glowHover` Keyboard Focus
+
+Add `focusin`/`focusout` listeners alongside `mouseenter`/`mouseleave`.
+
+### Missing ARIA States
+
+- Sound presets: `aria-pressed={$config.sound_preset === preset}`
+- Breathing patterns: `role="radiogroup"` wrapper, `role="radio"` + `aria-checked` on buttons
+- Color swatches: `aria-pressed={value === color}`
+
+---
+
+## Section 5: Timing & Notification Control
+
+### Toast Persistence
+
+All auto-dismissing elements (natural break toast, celebration overlay, goal badge):
+
+1. Track `hovering` via `mouseenter/leave` + `focusin/focusout`
+2. Auto-dismiss timer pauses while hovering
+3. Close button appears (sr-only "Dismiss notification")
+4. Escape key dismisses
+5. `role="alert"` + `aria-live="assertive"` kept
+
+### Breathing Guide Noise Fix
+
+Change breathing `aria-live` span to only announce phase changes (Inhale/Hold/Exhale), not countdown ticks. Track `lastAnnouncedPhase` and update live text only on phase name change.
+
+---
+
+## Section 6: ARIA Patterns & Semantic Enrichment
+
+### Section Accessible Names
+
+Add `id` to each heading, `aria-labelledby` on parent `<section>`.
+
+### Stats Tab Pattern
+
+- `role="tablist"` wrapper
+- `role="tab"` + `aria-selected` + `aria-controls` on each tab
+- `role="tabpanel"` + `id` + `aria-labelledby` on panels
+
+### Missing Data Tables
+
+Add sr-only `<table>` for 30-day chart and heatmap (matching existing 7-day pattern).
+
+### Additional ARIA
+
+- Daily goal bar: `role="progressbar"` + aria-value attributes
+- BreakOverlay: `role="alertdialog"` + `aria-label` + `<h2>`
+- MicrobreakOverlay: `role="alertdialog"` + `aria-label` + heading
+- Reset button: `aria-live="polite"` for confirmation state
+
+---
+
+## Section 7: Visual Presentation (1.4.8)
+
+### Line Spacing
+
+Default `leading-relaxed` (1.625) on body. Override with `leading-none` only on countdown numerics.
+
+### Text Selection
+
+Remove global `user-select: none`. Keep only on drag regions and decorative elements.
+
+### Skip Navigation
+
+Add skip link as first child of `<main>`: `<a href="#main-content" class="sr-only focus:not-sr-only">Skip to content</a>`.
+
+---
+
+## Section 8: Supplementary
+
+### Abbreviations
+
+Add `<abbr>` tags for standalone "s", "min", "h", "m" units. Add `title` on first use of Pomodoro, 20-20-20 in Settings.
+
+### Help Tooltips
+
+Add `title` attributes on complex settings (Pomodoro, Smart breaks, Microbreaks, Breathing).
+
+### Known Limitations
+
+- Canvas chart text spacing: Not fixable (Canvas API limitation). Sr-only data tables provide equivalent access.
+- Timer interruptions: Pause button effectively suppresses all breaks. No separate DND mode needed.

+# WCAG 2.2 AAA Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Achieve WCAG 2.2 AAA conformance across all frontend components while preserving the existing dark-theme visual identity.
+
+**Architecture:** All changes are CSS + Svelte template only — no Rust backend changes. Theme tokens in `app.css` propagate through Tailwind's `@theme` system. Components use Svelte 5 runes (`$state`, `$derived`, `$effect`, `$props`). Accessibility patterns follow WAI-ARIA 1.2 (tablist, radiogroup, alertdialog, progressbar).
+
+**Tech Stack:** Svelte 5, Tailwind CSS v4 (`@theme` tokens in CSS, no config file), TypeScript, Web Animations API (`motion` library)
+
+**Note:** This project has no frontend test suite. Verification is done via `npm run build` (Vite build) and manual inspection. Each task ends with a build check and a commit.
+
+---
+
+### Task 1: Theme Tokens & Global Styles (`app.css`)
+
+**Files:**
+- Modify: `break-timer/src/app.css` (entire file)
+
+This is the foundation — all subsequent tasks depend on these token changes.
+
+**Step 1: Update theme tokens**
+
+In `app.css`, inside the `@theme { }` block (lines 3–20):
+
+- Change `--color-text-sec: #8a8a8a` → `--color-text-sec: #a8a8a8` (7.28:1 on black)
+- Change `--color-text-dim: #3a3a3a` → `--color-text-dim: #5c5c5c` (3.5:1 decorative)
+- Change `--color-border: #222222` → `--color-border: #3a3a3a` (2.63:1 non-text)
+- Change `--color-danger: #f85149` → `--color-danger: #ff6b6b` (7.41:1)
+- Add new token: `--color-input-border: #444444;`
+- Add new token: `--color-surface-lt: #1e1e1e;`
+
+**Step 2: Update body styles**
+
+In the `html, body` block (lines 22–35):
+
+- Change `user-select: none` to only apply on drag regions:
+  - REMOVE `user-select: none;` and `-webkit-user-select: none;` from body
+  - ADD a new rule for drag regions only:
+    ```css
+    [data-tauri-drag-region],
+    [data-tauri-drag-region] * {
+      user-select: none;
+      -webkit-user-select: none;
+    }
+    ```
+- Add `line-height: 1.625;` (leading-relaxed) to body for AAA 1.4.8
+
+**Step 3: Enhance focus indicators**
+
+Replace the `:focus-visible` block (lines 73–76) with:
+
+```css
+:focus-visible {
+  outline: 2px solid var(--color-accent);
+  outline-offset: 2px;
+  box-shadow: 0 0 0 4px rgba(255, 255, 255, 0.3);
+}
+```
+
+The `box-shadow` provides a white fallback when the accent color has low contrast against dark backgrounds.
+
+**Step 4: Add skip link styles**
+
+After the `.sr-only` block, add:
+
+```css
+.skip-link {
+  position: absolute;
+  top: -100%;
+  left: 50%;
+  transform: translateX(-50%);
+  z-index: 10000;
+  padding: 8px 16px;
+  background: var(--color-accent);
+  color: #000;
+  font-size: 13px;
+  font-weight: 600;
+  border-radius: 0 0 8px 8px;
+  text-decoration: none;
+  transition: top 0.15s ease;
+}
+.skip-link:focus {
+  top: 0;
+}
+```
+
+**Step 5: Verify build**
+
+Run: `cd break-timer && npm run build`
+Expected: Build succeeds with no errors.
+
+**Step 6: Commit**
+
+```bash
+git add break-timer/src/app.css
+git commit -m "a11y: update theme tokens and global styles for WCAG AAA
+
+- Bump --color-text-sec to #a8a8a8 (7.28:1 contrast)
+- Bump --color-text-dim to #5c5c5c (3.5:1 decorative)
+- Bump --color-border to #3a3a3a (2.63:1 non-text)
+- Bump --color-danger to #ff6b6b (7.41:1)
+- Add --color-input-border and --color-surface-lt tokens
+- Add white shadow fallback on :focus-visible
+- Add leading-relaxed default line-height
+- Scope user-select:none to drag regions only
+- Add skip-link focus styles"
+```
+
+---
+
+### Task 2: App Shell (`App.svelte`)
+
+**Files:**
+- Modify: `break-timer/src/App.svelte`
+
+**Step 1: Add skip link**
+
+Inside the `<main>` element (line 87), add skip link as first child and an id target:
+
+```svelte
+<main class="relative h-full bg-black">
+  <a href="#main-content" class="skip-link">Skip to content</a>
+  ...
+```
+
+Then on the zoom container `<div>` (line 92), add `id="main-content"`:
+
+```svelte
+<div
+  id="main-content"
+  class="relative h-full overflow-hidden origin-top-left"
+```
+
+**Step 2: Add document title effect**
+
+After the existing focus management `$effect` (after line 76), add:
+
+```typescript
+// WCAG 2.4.2: Document title reflects current view
+$effect(() => {
+  const viewNames: Record<string, string> = {
+    dashboard: "Dashboard",
+    breakScreen: "Break",
+    settings: "Settings",
+    stats: "Statistics",
+  };
+  document.title = `Core Cooldown — ${viewNames[effectiveView] ?? "Dashboard"}`;
+});
+```
+
+**Step 3: Verify build**
+
+Run: `cd break-timer && npm run build`
+
+**Step 4: Commit**
+
+```bash
+git add break-timer/src/App.svelte
+git commit -m "a11y: add skip link and dynamic document title for WCAG AAA"
+```
+
+---
+
+### Task 3: Titlebar (`Titlebar.svelte`)
+
+**Files:**
+- Modify: `break-timer/src/lib/components/Titlebar.svelte`
+
+**Step 1: Wrap in header landmark**
+
+Change the outer `<div>` (line 8) to `<header role="banner">`.
+
+**Step 2: Enlarge traffic lights to meet 44px target size**
+
+Change each traffic light button from `h-[15px] w-[15px]` to `h-[20px] w-[20px]` visual size with `min-h-[44px] min-w-[44px]` hit area via padding. The trick: keep the visual circle at 20px but wrap in a 44px invisible tap area.
+
+Replace each button's class. For example the Maximize button (line 27):
+
+```svelte
+<button
+  aria-label="Maximize"
+  class="traffic-btn group/btn relative flex h-[44px] w-[44px] items-center justify-center"
+  onclick={() => appWindow.toggleMaximize()}
+>
+  <span class="flex h-[20px] w-[20px] items-center justify-center rounded-full bg-[#27C93F] transition-all duration-150 group-hover/btn:brightness-110">
+    <svg ...>
+  </span>
+</button>
+```
+
+Apply the same pattern to Minimize and Close buttons. The gap between buttons changes from `gap-[8px]` to `gap-0` since the 44px buttons provide their own spacing.
+
+**Step 3: Verify build**
+
+Run: `cd break-timer && npm run build`
+
+**Step 4: Commit**
+
+```bash
+git add break-timer/src/lib/components/Titlebar.svelte
+git commit -m "a11y: add header landmark and enlarge traffic lights to 44px hit areas"
+```
+

+- Modify: `break-timer/src/lib/components/ToggleSwitch.svelte`
+
+**Step 1: Enlarge to 52x28 and fix knob contrast**
+
+Change button dimensions from `h-[24px] w-[48px]` to `h-[28px] w-[52px]` with `min-h-[44px]` padding for hit area.
+
+Change the knob span from `h-[19px] w-[19px]` to `h-[22px] w-[22px]`.
+Change translate-x for ON state from `translate-x-[26px]` to `translate-x-[27px]`.
+Change mt from `mt-[2.5px]` to `mt-[3px]`.
+Change OFF knob color from `bg-[#444]` to `bg-[#666]` (better contrast).
+
+The button should have `min-h-[44px]` via a wrapper approach or padding.
+
+**Step 2: Verify build**
+
+Run: `cd break-timer && npm run build`
+
+**Step 3: Commit**
+
+```bash
+git add break-timer/src/lib/components/ToggleSwitch.svelte
+git commit -m "a11y: enlarge toggle switch and improve OFF knob contrast"

+
+### Task 5: Stepper (`Stepper.svelte`)
+
+**Files:**
+- Modify: `break-timer/src/lib/components/Stepper.svelte`
+
+**Step 1: Enlarge buttons and fix contrast**
+
+Change both +/- button dimensions from `h-7 w-7` (28px) to `h-9 w-9` (36px) with `min-h-[44px] min-w-[44px]` padding.
+
+Change `bg-[#141414]` to `bg-[#1a1a1a] border border-[#3a3a3a]` for better non-text contrast.
+
+Change `text-[#8a8a8a]` to `text-text-sec` (uses updated theme token).
+
+**Step 2: Add keyboard hold-to-repeat**
+
+Add `onkeydown` handlers to both buttons that trigger the same `startHold`/`stopHold` logic for Enter, Space, ArrowUp, ArrowDown keys:
+
+```typescript
+function handleKeydown(fn: () => void, e: KeyboardEvent) {
+  if (["Enter", " ", "ArrowUp", "ArrowDown"].includes(e.key)) {
+    e.preventDefault();
+    startHold(e.key === "ArrowDown" || e.key === "ArrowUp" ? fn : fn);
+  }
+}
+
+function handleKeyup(e: KeyboardEvent) {
+  if (["Enter", " ", "ArrowUp", "ArrowDown"].includes(e.key)) {
+    stopHold();
+  }
+}
+```
+
+Add `onkeydown` and `onkeyup` to both buttons. The decrease button uses ArrowDown for decrement, the increase button uses ArrowUp for increment.
+
+**Step 3: Verify build**
+
+Run: `cd break-timer && npm run build`
+
+**Step 4: Commit**
+
+```bash
+git add break-timer/src/lib/components/Stepper.svelte
+git commit -m "a11y: enlarge stepper buttons and add keyboard hold-to-repeat"
+```
+
+---
+
+### Task 6: Animation Actions (`animate.ts`)
+
+**Files:**
+- Modify: `break-timer/src/lib/utils/animate.ts`
+
+**Step 1: Add keyboard support to `pressable`**
+
+In the `pressable` function (line 117), after the mousedown/mouseup/mouseleave listeners (lines 143–145), add keydown/keyup for Enter and Space:
+
+```typescript
+function onKeyDown(e: KeyboardEvent) {
+  if (e.key === "Enter" || e.key === " ") {
+    e.preventDefault();
+    onDown();
+  }
+}
+
+function onKeyUp(e: KeyboardEvent) {
+  if (e.key === "Enter" || e.key === " ") {
+    onUp();
+  }
+}
+
+node.addEventListener("keydown", onKeyDown);
+node.addEventListener("keyup", onKeyUp);
+```
+
+Update `destroy()` to remove these listeners too.
+
+**Step 2: Add focus support to `glowHover`**
+
+In the `glowHover` function (line 165), after mouseenter/mouseleave listeners (lines 201–202), add focusin/focusout:
+
+```typescript
+node.addEventListener("focusin", onEnter);
+node.addEventListener("focusout", onLeave);
+```
+
+Update `destroy()` to remove these listeners too.
+
+**Step 3: Verify build**
+
+Run: `cd break-timer && npm run build`
+
+**Step 4: Commit**
+
+```bash
+git add break-timer/src/lib/utils/animate.ts

+
+### Task 7: Dashboard (`Dashboard.svelte`)
+
+**Files:**
+- Modify: `break-timer/src/lib/components/Dashboard.svelte`
+
+**Step 1: Replace hardcoded `#8a8a8a` with theme token**
+
+Replace all `text-[#8a8a8a]` with `text-text-sec` throughout the file. There are ~10 instances on lines 180, 208, 216, 234, 241, 256, 301, 329, 361.
+
+Replace `border-[#222]` with `border-border` on the three bottom buttons (lines 302, 328, 360).
+
+**Step 2: Wrap bottom buttons in nav landmark**
+
+Around the three bottom action buttons (lines 296–382), wrap in:
+
+```svelte
+<nav aria-label="Main actions">
+  <!-- Bottom left: start break now -->
+  ...
+  <!-- Bottom center: stats -->
+  ...
+  <!-- Bottom right: settings -->
+  ...
+</nav>
+```
+
+The three `<div class="absolute bottom-5 ...">` blocks move inside the `<nav>`.
+
+**Step 3: Make natural break toast persistent on hover**
+
+Replace the simple timeout logic (lines 118–126) with hover-aware persistence:
+
+```typescript
+let toastHovering = $state(false);
+
+$effect(() => {
+  if ($timer.naturalBreakOccurred) {
+    showNaturalBreakToast = true;
+    if (naturalBreakToastTimeout) clearTimeout(naturalBreakToastTimeout);
+    naturalBreakToastTimeout = setTimeout(() => {
+      if (!toastHovering) showNaturalBreakToast = false;
+    }, 5000);
+  }
+});
+```
+
+On the toast div (line 266), add:
+
+```svelte
+onmouseenter={() => toastHovering = true}
+onmouseleave={() => { toastHovering = false; showNaturalBreakToast = false; }}
+onfocusin={() => toastHovering = true}
+onfocusout={() => { toastHovering = false; showNaturalBreakToast = false; }}
+```
+
+Add a close button inside the toast and an Escape key handler.
+
+**Step 4: Add progressbar role to daily goal bar**
+
+On the goal progress bar div (line 235), add ARIA:
+
+```svelte
+<div class="w-16 h-[2px] rounded-full overflow-hidden" style="background: #161616;"
+  role="progressbar"
+  aria-label="Daily goal progress"
+  aria-valuemin={0}
+  aria-valuemax={$config.daily_goal_breaks}
+  aria-valuenow={dailyGoalProgress}
+>
+```
+
+**Step 5: Add sr-only text for pomodoro dots**
+
+After the pomodoro dots visual `<div>` (around line 192), add:
+
+```svelte
+<span class="sr-only">
+  Pomodoro cycle: session {$timer.pomodoroCyclePosition + 1} of {$timer.pomodoroTotalInCycle}
+</span>
+```
+
+**Step 6: Verify build**
+
+Run: `cd break-timer && npm run build`
+
+**Step 7: Commit**
+
+```bash
+git add break-timer/src/lib/components/Dashboard.svelte
+git commit -m "a11y: dashboard contrast, nav landmark, toast persistence, goal progressbar"

+
+### Task 8: Settings — Part 1: Headings & Structure (`Settings.svelte`)
+
+**Files:**
+- Modify: `break-timer/src/lib/components/Settings.svelte`
+
+This is a large file (1176 lines). Split into two commits for reviewability.
+
+**Step 1: Change all `<h3>` to `<h2>`**
+
+Replace every `<h3 class="mb-4 text-[11px] ...` with `<h2 class="mb-4 text-[11px] ...` and corresponding `</h3>` with `</h2>`. There are 17 instances at approximate lines: 163, 218, 280, 346, 435, 444, 498, 590, 668, 732, 825, 862, 906, 976(Working Hours has no heading — add one), 1078, 1119, 1138.
+
+**Step 2: Add `id` to headings and `aria-labelledby` to sections**
+
+Each `<section>` gets an `aria-labelledby` pointing to its heading's `id`. Pattern:
+
+```svelte
+<section aria-labelledby="settings-timer" class="rounded-2xl p-5 ...">
+  <h2 id="settings-timer" class="mb-4 ...">Timer</h2>
+```
+
+Do this for all 18 sections. Use ids: `settings-timer`, `settings-pomodoro`, `settings-microbreaks`, `settings-breakscreen`, `settings-activities`, `settings-breathing`, `settings-behavior`, `settings-alerts`, `settings-sound`, `settings-idle`, `settings-presentation`, `settings-goals`, `settings-appearance`, `settings-workinghours`, `settings-minimode`, `settings-general`, `settings-shortcuts`.
+
+**Step 3: Add missing heading for Working Hours section**
+
+The Working Hours section (line 975) has no `<h3>`/`<h2>`. Add:
+
+```svelte
+<h2 id="settings-workinghours" class="mb-4 text-[11px] font-medium tracking-[0.15em] text-text-sec uppercase">
+  Working Hours
+</h2>
+```
+
+**Step 4: Verify build**
+
+Run: `cd break-timer && npm run build`
+
+**Step 5: Commit**
+
+```bash
+git add break-timer/src/lib/components/Settings.svelte
+git commit -m "a11y: settings heading hierarchy (h3→h2) and section landmarks"
+```
+

+
+### Task 9: Settings — Part 2: ARIA, Contrast, Sizes (`Settings.svelte`)
+
+**Files:**
+- Modify: `break-timer/src/lib/components/Settings.svelte`
+
+**Step 1: Breathing pattern — radiogroup/radio**
+
+Wrap the breathing pattern buttons (line 464) in a `role="radiogroup"` container:
+
+```svelte
+<div role="radiogroup" aria-label="Breathing pattern" class="flex flex-col gap-1.5">
+```
+
+Each breathing pattern button gets `role="radio"` and `aria-checked`:
+
+```svelte
+<button
+  role="radio"
+  aria-checked={$config.breathing_pattern === bp.id}
+  ...
+```
+
+**Step 2: Sound preset — aria-pressed**
+
+Each sound preset button (line 709) gets `aria-pressed`:
+
+```svelte
+<button
+  aria-pressed={$config.sound_preset === preset}
+  ...
+```
+
+**Step 3: Replace hardcoded colors**
+
+- All `text-[#8a8a8a]` → `text-text-sec` (many instances throughout)
+- All `bg-[#161616]` dividers → `bg-border` (use `--color-border` token)
+- All `border-[#161616]` on inputs → `border-border`
+- All `placeholder:text-[#2a2a2a]` → `placeholder:text-[#555]` (3.37:1)
+- All `bg-[#141414]` → use updated stepper component (already handled in Task 5)
+- Back button `h-8 w-8` → `h-10 w-10 min-h-[44px] min-w-[44px]` (line 127)
+
+**Step 4: Reset button aria-live**
+
+Wrap the reset button text in an `aria-live="polite"` region, or add `aria-live="polite"` to the button itself so screen readers announce the confirmation state change:
+
+```svelte
+<button
+  aria-live="polite"
+  ...
+>
+  {resetConfirming ? "Tap again to confirm reset" : "Reset to defaults"}
+</button>
+```
+
+**Step 5: Add abbreviation tags**
+
+For standalone unit abbreviations in setting descriptions, wrap with `<abbr>`:
+
+- `"s"` (seconds) → `<abbr title="seconds">s</abbr>`
+- `"min"` → `<abbr title="minutes">min</abbr>`
+
+Apply on first occurrence in: alert timing description (line 613), idle timeout (line 755), snooze duration (line 537).
+
+**Step 6: Add title tooltips on complex settings**
+
+Add `title` attributes on the section-level labels for Pomodoro, Smart breaks, Microbreaks, Breathing:
+
+- Pomodoro `<h2>`: `title="Pomodoro technique alternates focused work sessions with short and long breaks"`
+- Microbreaks `<h2>`: `title="20-20-20 rule: every 20 minutes, look 20 feet away for 20 seconds"`
+- Smart breaks `<div>`: `title="Automatically counts time away from computer as a break"`
+- Breathing guide `<h2>`: `title="Visual breathing exercise during breaks to reduce stress"`
+
+**Step 7: Verify build**
+
+Run: `cd break-timer && npm run build`
+
+**Step 8: Commit**
+
+```bash
+git add break-timer/src/lib/components/Settings.svelte
+git commit -m "a11y: settings ARIA patterns, contrast, abbreviations, and tooltips"
+```

+
+### Task 10: StatsView — Tabs & Data Tables (`StatsView.svelte`)
+
+**Files:**
+- Modify: `break-timer/src/lib/components/StatsView.svelte`
+
+**Step 1: Change all `<h3>` to `<h2>`**
+
+Replace all `<h3>` with `<h2>` and `</h3>` with `</h2>` (~12 instances).
+
+**Step 2: Implement tablist pattern**
+
+Replace the tab navigation (lines 297–310):
+
+```svelte
+<div role="tablist" aria-label="Statistics time range" class="flex gap-1 px-5 mb-3" use:fadeIn={{ duration: 0.3, y: 6 }}>
+  {#each [["today", "Today"], ["weekly", "Weekly"], ["monthly", "Monthly"]] as [tab, label]}
+    <button
+      role="tab"
+      aria-selected={activeTab === tab}
+      aria-controls="tabpanel-{tab}"
+      id="tab-{tab}"
+      use:pressable
+      class="rounded-lg px-4 py-2 min-h-[44px] text-[11px] tracking-wider uppercase transition-all duration-200
+             {activeTab === tab
+               ? 'bg-[#1a1a1a] text-white'
+               : 'text-text-sec hover:text-white'}"
+      onclick={() => activeTab = tab as any}
+    >
+      {label}
+    </button>
+  {/each}
+</div>
+```
+
+Wrap each tab's content in a `role="tabpanel"`:
+
+```svelte
+{#if activeTab === "today"}
+  <div role="tabpanel" id="tabpanel-today" aria-labelledby="tab-today">
+    ...
+  </div>
+```
+
+Same for `weekly` and `monthly`.
+
+**Step 3: Add sr-only data tables for 30-day chart and heatmap**
+
+After the 30-day chart canvas (around line 533), add:
+
+```svelte
+{#if monthHistory.length > 0}
+  <table class="sr-only">
+    <caption>Break history for the last {monthHistory.length} days</caption>
+    <thead>
+      <tr><th>Date</th><th>Completed</th><th>Skipped</th></tr>
+    </thead>
+    <tbody>
+      {#each monthHistory as day}
+        <tr><td>{day.date}</td><td>{day.breaksCompleted}</td><td>{day.breaksSkipped}</td></tr>
+      {/each}
+    </tbody>
+  </table>
+{/if}
+```
+
+After the heatmap canvas (around line 559), add:
+
+```svelte
+{#if monthHistory.length > 0}
+  <table class="sr-only">
+    <caption>Activity heatmap for the last {monthHistory.length} days</caption>
+    <thead>
+      <tr><th>Date</th><th>Breaks completed</th></tr>
+    </thead>
+    <tbody>
+      {#each monthHistory as day}
+        <tr><td>{day.date}</td><td>{day.breaksCompleted}</td></tr>
+      {/each}
+    </tbody>
+  </table>
+{/if}
+```
+
+**Step 4: Replace hardcoded colors**
+
+- All `text-[#8a8a8a]` → `text-text-sec`
+- `bg-[#161616]` dividers → `bg-border`
+- Back button: `h-8 w-8` → `h-10 w-10 min-h-[44px] min-w-[44px]`
+
+**Step 5: Verify build**
+
+Run: `cd break-timer && npm run build`
+
+**Step 6: Commit**
+
+```bash
+git add break-timer/src/lib/components/StatsView.svelte
+git commit -m "a11y: stats tablist pattern, sr-only data tables, contrast updates"
+```
+

+
+### Task 11: BreakScreen (`BreakScreen.svelte`)
+
+**Files:**
+- Modify: `break-timer/src/lib/components/BreakScreen.svelte`
+
+**Step 1: Add strict mode focus safety**
+
+When `strict_mode` is true and buttons are hidden, the focus trap has zero focusable elements. After the `{#if showButtons}` block (around line 353 for in-app, line 203 for standalone), add an else block:
+
+```svelte
+{:else}
+  <span tabindex="0" class="sr-only" aria-live="polite">
+    Break in progress, please wait
+  </span>
+{/if}
+```
+
+This ensures the focus trap always has at least one focusable element.
+
+**Step 2: Fix breathing aria-live to only announce phase changes**
+
+The breathing guide `<span aria-live="polite">` (lines 172 and 304) currently announces every countdown tick. Add a tracked variable that only updates on phase change:
+
+In the script section, add:
+
+```typescript
+let lastAnnouncedPhase = $state("");
+let breathAnnouncement = $derived(
+  breathPhase !== lastAnnouncedPhase
+    ? (() => { lastAnnouncedPhase = breathPhase; return `${breathPhase}`; })()
+    : ""
+);
+```
+
+Actually, better approach — use a separate `$effect` and a dedicated announcement state:
+
+```typescript
+let breathAnnouncement = $state("");
+$effect(() => {
+  // Only announce when the breathing phase name changes, not countdown ticks
+  breathAnnouncement = breathPhase;
+});
+```
+
+Then change the aria-live span to use a separate invisible span for SR announcements:
+
+```svelte
+<span class="sr-only" aria-live="polite" aria-atomic="true">{breathAnnouncement}</span>
+```
+
+Keep the visible breathing text without `aria-live` (remove `aria-live="polite"` from the visible span).
+
+**Step 3: Replace hardcoded colors**
+
+- `text-[#8a8a8a]` → `text-text-sec`
+- `border-[#222]` → `border-border`
+
+**Step 4: Verify build**
+
+Run: `cd break-timer && npm run build`
+
+**Step 5: Commit**
+
+```bash
+git add break-timer/src/lib/components/BreakScreen.svelte
+git commit -m "a11y: break screen strict-mode focus safety and breathing phase announcements"

+
+### Task 12: Celebration Toast Persistence (`Celebration.svelte`)
+
+**Files:**
+- Modify: `break-timer/src/lib/components/Celebration.svelte`
+
+**Step 1: Add hover/focus-aware auto-dismiss**
+
+Replace the CSS-driven 3.5s fade with JS-controlled timing. Add state:
+
+```typescript
+let milestoneHovering = $state(false);
+let goalHovering = $state(false);
+```
+
+For the `.celebration-overlay` div, add:
+
+```svelte
+onmouseenter={() => milestoneHovering = true}
+onmouseleave={() => milestoneHovering = false}
+onfocusin={() => milestoneHovering = true}
+onfocusout={() => milestoneHovering = false}
+```
+
+Remove `pointer-events: none` from `.celebration-overlay` and `.goal-overlay` styles.
+
+Add `$effect` blocks that manage visibility based on hover state — when not hovering, set a timeout to add a CSS class that triggers fade-out.
+
+Add a close button (sr-only label "Dismiss notification") to both overlays, and an Escape key handler.
+
+**Step 2: Verify build**
+
+Run: `cd break-timer && npm run build`
+
+**Step 3: Commit**

+
+Change the outer `.microbreak-card` div (line 41):
+
+```svelte
+<div class="microbreak-card" role="alertdialog" aria-label="Microbreak" aria-describedby="microbreak-msg">
+  <h2 class="sr-only">Microbreak</h2>
+  <div class="flex items-center gap-3 mb-2">

+### Task 18: Final Build Verification & Cleanup
+
+**Step 1: Full build**
+
+Run: `cd break-timer && npm run build`
+Expected: Build succeeds with zero errors.
+
+**Step 2: Verify all theme token propagation**
+
+Search for any remaining hardcoded `#8a8a8a` in Svelte files — there should be none (all replaced with `text-text-sec` or inline `#a8a8a8`).
+
+Run: `grep -r "#8a8a8a" break-timer/src/` — should return zero results.
+
+**Step 3: Verify no remaining h3 headings in Settings/Stats**
+
+Run: `grep -n "<h3" break-timer/src/lib/components/Settings.svelte break-timer/src/lib/components/StatsView.svelte` — should return zero results.
+
+**Step 4: Final commit if any cleanup needed**
+
+```bash
+git add -A break-timer/src/
+git commit -m "a11y: final cleanup pass for WCAG 2.2 AAA compliance"
+```
