# WCAG 2.2 AAA Compliance Implementation Plan

> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.

**Goal:** Make Driftwood fully WCAG 2.2 AAA compliant across all four principles (Perceivable, Operable, Understandable, Robust).

**Architecture:** Hybrid approach - centralized accessibility helpers in `widgets.rs` for repeated patterns (labeled buttons, live announcements, described badges), plus direct `update_property`/`update_state`/`update_relation` calls in each UI file for unique cases. CSS additions in `style.css` for focus indicators, high-contrast mode, reduced-motion expansion, and target sizes.

**Tech Stack:** Rust, gtk4-rs (0.11), libadwaita-rs (0.9), GTK4 accessible API (`gtk::accessible::Property`, `gtk::accessible::State`, `gtk::accessible::Relation`, `gtk::AccessibleRole`)

---

### Task 1: CSS Foundation - Focus Indicators, High Contrast, Reduced Motion, Target Sizes

**Files:**
- Modify: `data/resources/style.css`

**Step 1: Add universal focus-visible indicators**

Append after the existing `flowboxchild:focus-visible .app-card` block (line 91). These ensure every focusable widget has a visible 2px accent-color outline meeting WCAG 2.4.7 and 2.4.13:

```css
/* ===== WCAG AAA Focus Indicators ===== */
button:focus-visible,
togglebutton:focus-visible,
menubutton:focus-visible,
checkbutton:focus-visible,
switch:focus-visible,
entry:focus-visible,
searchentry:focus-visible,
spinbutton:focus-visible {
    outline: 2px solid @accent_bg_color;
    outline-offset: 2px;
}

row:focus-visible {
    outline: 2px solid @accent_bg_color;
    outline-offset: -2px;
}
```

**Step 2: Add high-contrast media query**

Append a `prefers-contrast: more` section (WCAG 1.4.6 Enhanced Contrast, 1.4.11 Non-text Contrast):

```css
/* ===== High Contrast Mode (WCAG AAA 1.4.6) ===== */
@media (prefers-contrast: more) {
    .app-card {
        border: 2px solid @window_fg_color;
    }

    flowboxchild:focus-visible .app-card {
        outline-width: 3px;
    }

    button:focus-visible,
    togglebutton:focus-visible,
    menubutton:focus-visible,
    checkbutton:focus-visible,
    switch:focus-visible,
    entry:focus-visible,
    searchentry:focus-visible,
    spinbutton:focus-visible {
        outline-width: 3px;
    }

    row:focus-visible {
        outline-width: 3px;
    }

    .status-badge,
    .status-badge-with-icon {
        border: 1px solid currentColor;
    }

    .compat-warning-banner {
        border: 2px solid @warning_bg_color;
    }
}
```

**Step 3: Expand reduced-motion to cover ALL transitions (WCAG 2.3.3)**

Replace the existing `@media (prefers-reduced-motion: reduce)` block (lines 152-160) with:

```css
/* ===== Reduced Motion (WCAG AAA 2.3.3) ===== */
@media (prefers-reduced-motion: reduce) {
    * {
        transition-duration: 0 !important;
        transition-delay: 0 !important;
        animation-duration: 0 !important;
        animation-delay: 0 !important;
    }
}
```

**Step 4: Add minimum target size (WCAG 2.5.8)**

```css
/* ===== Minimum Target Size (WCAG 2.5.8) ===== */
button.flat.circular,
button.flat:not(.pill):not(.suggested-action):not(.destructive-action) {
    min-width: 24px;
    min-height: 24px;
}
```

**Step 5: Build to verify CSS loads**

Run: `cargo build 2>&1 | tail -5`
Expected: success (CSS is loaded at runtime, not compiled)

**Step 6: Commit**

```
git add data/resources/style.css
git commit -m "Add WCAG AAA focus indicators, high-contrast mode, and reduced-motion coverage"
```

### Task 2: Accessibility Helpers in widgets.rs

**Files:**
- Modify: `src/ui/widgets.rs`

**Step 1: Add accessible label to copy_button**

In the `copy_button` function (line 129-149), add an accessible label after creating the button. Change:

```rust
pub fn copy_button(text_to_copy: &str, toast_overlay: Option<&adw::ToastOverlay>) -> gtk::Button {
    let btn = gtk::Button::builder()
        .icon_name("edit-copy-symbolic")
        .tooltip_text("Copy to clipboard")
        .valign(gtk::Align::Center)
        .build();
    btn.add_css_class("flat");
```

To:

```rust
pub fn copy_button(text_to_copy: &str, toast_overlay: Option<&adw::ToastOverlay>) -> gtk::Button {
    let btn = gtk::Button::builder()
        .icon_name("edit-copy-symbolic")
        .tooltip_text("Copy to clipboard")
        .valign(gtk::Align::Center)
        .build();
    btn.add_css_class("flat");
    btn.update_property(&[gtk::accessible::Property::Label("Copy to clipboard")]);
```

**Step 2: Add accessible description to status_badge**

Update `status_badge` (lines 5-10) to include a `RoleDescription`:

```rust
pub fn status_badge(text: &str, style_class: &str) -> gtk::Label {
    let label = gtk::Label::new(Some(text));
    label.add_css_class("status-badge");
    label.add_css_class(style_class);
    label.set_accessible_role(gtk::AccessibleRole::Status);
    label
}
```

**Step 3: Add accessible role to status_badge_with_icon**

Update `status_badge_with_icon` (lines 14-30) similarly:

```rust
pub fn status_badge_with_icon(icon_name: &str, text: &str, style_class: &str) -> gtk::Box {
    let hbox = gtk::Box::builder()
        .orientation(gtk::Orientation::Horizontal)
        .spacing(4)
        .accessible_role(gtk::AccessibleRole::Status)
        .build();
    hbox.add_css_class("status-badge-with-icon");
    hbox.add_css_class(style_class);
    hbox.update_property(&[gtk::accessible::Property::Label(text)]);

    let icon = gtk::Image::from_icon_name(icon_name);
    icon.set_pixel_size(12);
    hbox.append(&icon);

    let label = gtk::Label::new(Some(text));
    hbox.append(&label);

    hbox
}
```

**Step 4: Add `announce()` live region helper function**

Add at the end of `widgets.rs`:

```rust
/// Create a screen-reader live region announcement.
/// Inserts a hidden label with AccessibleRole::Alert into the given container,
/// which causes AT-SPI to announce the text to screen readers.
/// The label auto-removes after a short delay.
pub fn announce(container: &impl gtk::prelude::IsA<gtk::Widget>, text: &str) {
    let label = gtk::Label::builder()
        .label(text)
        .visible(false)
        .accessible_role(gtk::AccessibleRole::Alert)
        .build();
    label.update_property(&[gtk::accessible::Property::Label(text)]);

    // We need to add it to a container to make it part of the accessible tree.
    // Use the widget's first ancestor that is a Box, or fall back to toast overlay.
    // Since we cannot generically append to any widget, the caller should pass
    // a gtk::Box or adw::ToastOverlay.
    if let Some(box_widget) = container.dynamic_cast_ref::<gtk::Box>() {
        box_widget.append(&label);
        // Make visible briefly so AT-SPI picks it up, then remove
        label.set_visible(true);
        let label_clone = label.clone();
        let box_clone = box_widget.clone();
        glib::timeout_add_local_once(std::time::Duration::from_millis(500), move || {
            box_clone.remove(&label_clone);
        });
    }
}
```

**Step 5: Add `use gtk::prelude::*;` import check**

The file already has `use gtk::prelude::*;` at line 1. No change needed.

**Step 6: Build to verify**

Run: `cargo build 2>&1 | tail -5`
Expected: success with zero errors

**Step 7: Commit**

```
git add src/ui/widgets.rs
git commit -m "Add WCAG accessibility helpers: labeled badges, live announcements, copy button label"
```

---

### Task 3: Library View Accessible Labels and Roles

**Files:**

scan_now_btn.update_property(&[AccessibleProperty::Label("Scan for AppImages")]);
```

After line 162 (prefs_btn):

```rust
prefs_btn.update_property(&[AccessibleProperty::Label("Open preferences")]);
```

**Step 3: Add accessible label to list_box**

After line 214 (`list_box.add_css_class("boxed-list");`):

```rust
list_box.update_property(&[AccessibleProperty::Label("AppImage library list")]);
```

**Step 4: Add AccessibleRole::Search to search_bar**

After line 118 (`search_bar.connect_entry(&search_entry);`):

```rust
search_bar.set_accessible_role(gtk::AccessibleRole::Search);
```

**Step 5: Build and verify**

Run: `cargo build 2>&1 | tail -5`
Expected: success with zero errors

**Step 6: Commit**

```
git add src/ui/library_view.rs
git commit -m "Add WCAG accessible labels to library view buttons, list box, and search bar"
```

### Task 4: App Card Accessible Emblem Description

**Files:**
- Modify: `src/ui/app_card.rs`

**Step 1: Add accessible description to integration emblem**

In `build_app_card` (line 32-43), after creating the emblem overlay, add a description. Change:

```rust
    if record.integrated {
        let overlay = gtk::Overlay::new();
        overlay.set_child(Some(&icon_widget));

        let emblem = gtk::Image::from_icon_name("emblem-ok-symbolic");
        emblem.set_pixel_size(16);
        emblem.add_css_class("integration-emblem");
        emblem.set_halign(gtk::Align::End);
        emblem.set_valign(gtk::Align::End);
        overlay.add_overlay(&emblem);

        card.append(&overlay);
```

To:

```rust
    if record.integrated {
        let overlay = gtk::Overlay::new();
        overlay.set_child(Some(&icon_widget));

        let emblem = gtk::Image::from_icon_name("emblem-ok-symbolic");
        emblem.set_pixel_size(16);
        emblem.add_css_class("integration-emblem");
        emblem.set_halign(gtk::Align::End);
        emblem.set_valign(gtk::Align::End);
        emblem.update_property(&[AccessibleProperty::Label("Integrated into desktop menu")]);
        overlay.add_overlay(&emblem);

        card.append(&overlay);
```

**Step 2: Build and verify**

Run: `cargo build 2>&1 | tail -5`
Expected: success

**Step 3: Commit**

```
git add src/ui/app_card.rs
git commit -m "Add accessible label to integration emblem overlay in app cards"
```

**Files:**
- Modify: `src/ui/detail_view.rs`

**Step 1: Add accessible role to banner**

In `build_banner` (line 160), after `banner.add_css_class("detail-banner");`, add:

```rust
banner.set_accessible_role(gtk::AccessibleRole::Banner);
```

**Step 2: Add tooltips for technical terms**

In `build_system_integration_group`:

For the Wayland row (around line 315), change:
```rust
    let wayland_row = adw::ActionRow::builder()
        .title("Wayland")
        .subtitle(wayland_description(&wayland_status))
        .build();
```
To:
```rust
    let wayland_row = adw::ActionRow::builder()
        .title("Wayland")
        .subtitle(wayland_description(&wayland_status))
        .tooltip_text("Display protocol for Linux desktops")
        .build();
```

For the FUSE row (around line 389), change:
```rust
    let fuse_row = adw::ActionRow::builder()
        .title("FUSE")
        .subtitle(fuse_description(&fuse_status))
        .build();
```
To:
```rust
    let fuse_row = adw::ActionRow::builder()
        .title("FUSE")
        .subtitle(fuse_description(&fuse_status))
        .tooltip_text("Filesystem in Userspace - required for mounting AppImages")
        .build();
```

For the Firejail row (around line 432), change:
```rust
    let firejail_row = adw::SwitchRow::builder()

        .title("Firejail sandbox")
        .tooltip_text("Linux application sandboxing tool")
```

**Step 3: Plain language rewrites in build_updates_usage_group**

Change line ~507 from:
```rust
            .subtitle("No update information embedded")
```
To:
```rust
            .subtitle("This app cannot check for updates automatically")
```

**Step 4: Add tooltip to SHA256 row**

In `build_security_storage_group`, for the SHA256 row (around line 830), change:
```rust
        let hash_row = adw::ActionRow::builder()
            .title("SHA256")
```
To:
```rust
        let hash_row = adw::ActionRow::builder()
            .title("SHA256 checksum")
            .tooltip_text("Cryptographic hash for verifying file integrity")
```

**Step 5: Add tooltip to AppImage type row**

Change (around line 815):
```rust
    let type_row = adw::ActionRow::builder()
        .title("AppImage type")
        .subtitle(type_str)
        .build();
```

        .tooltip_text("Type 1 uses ISO9660, Type 2 uses SquashFS")
        .build();
```

**Step 6: Add busy state to security scan row**

In the security scan `connect_activated` closure (around line 640-670), add busy state when scan starts and clear when done.

After `row.set_sensitive(false);` add:
```rust
        row.update_state(&[gtk::accessible::State::Busy(true)]);
```

After `row_clone.set_sensitive(true);` add:
```rust
            row_clone.update_state(&[gtk::accessible::State::Busy(false)]);

---

### Task 6: Dashboard Tooltips for Technical Terms

**Files:**
- Modify: `src/ui/dashboard.rs`

**Step 1: Add tooltips to system status rows**

For the FUSE row (around line 97), change:
```rust
    let fuse_row = adw::ActionRow::builder()
        .title("FUSE")
        .subtitle(&fuse_description(&fuse_info))
        .build();

### Task 7: Duplicate Dialog - Accessible Labels and Confirmation

**Files:**
- Modify: `src/ui/duplicate_dialog.rs`

**Step 1: Add accessible label to bulk remove button**

After the bulk_btn is created (around line 41-46), add:

```rust
    bulk_btn.update_property(&[
        gtk::accessible::Property::Label("Remove all suggested duplicates"),
    ]);
```

**Step 2: Add accessible label to per-row delete buttons**

In `build_group_widget`, after the delete_btn is created (around line 195-201), add:

```rust
            delete_btn.update_property(&[
                gtk::accessible::Property::Label(&format!("Delete {}", record_name)),
            ]);
```

(This line must go after the `record_name` variable is created at line 205.)

Actually, re-checking the code structure - `record_name` is defined at line 205 and `delete_btn` at line 195. We need to move the accessible label after `record_name` is defined. Add after line 205:

```rust
            delete_btn.update_property(&[
                gtk::accessible::Property::Label(&format!("Delete {}", record_name)),
            ]);
```

**Step 3: Add confirmation to bulk remove**

Wrap the bulk_btn `connect_clicked` handler (lines 95-115) to show a confirmation AlertDialog first. Replace the entire `bulk_btn.connect_clicked` block:

```rust
    let parent_for_confirm = dialog.clone();
    bulk_btn.connect_clicked(move |btn| {
        let records = removable.borrow();
        if records.is_empty() {
            return;
        }
        let count = records.len();
        let confirm = adw::AlertDialog::builder()
            .heading("Confirm Removal")
            .body(&format!("Remove {} suggested duplicate{}?", count, if count == 1 { "" } else { "s" }))
            .close_response("cancel")
            .default_response("remove")
            .build();
        confirm.add_response("cancel", "Cancel");
        confirm.add_response("remove", "Remove");
        confirm.set_response_appearance("remove", adw::ResponseAppearance::Destructive);

        let db_bulk = db_bulk.clone();
        let toast_bulk = toast_bulk.clone();
        let removable_inner = removable.clone();
        let btn_clone = btn.clone();
        confirm.connect_response(None, move |_dlg, response| {
            if response != "remove" {
                return;
            }
            let records = removable_inner.borrow();
            let mut removed_count = 0;
            for (record_id, record_path, _record_name, integrated) in records.iter() {
                if *integrated {
                    if let Ok(Some(full_record)) = db_bulk.get_appimage_by_id(*record_id) {
                        integrator::remove_integration(&full_record).ok();
                    }
                    db_bulk.set_integrated(*record_id, false, None).ok();
                }
                std::fs::remove_file(record_path).ok();
                db_bulk.remove_appimage(*record_id).ok();
                removed_count += 1;
            }
            if removed_count > 0 {
                toast_bulk.add_toast(adw::Toast::new(&format!("Removed {} items", removed_count)));
                btn_clone.set_sensitive(false);
                btn_clone.set_label("Done");
            }
        });
        confirm.present(Some(&parent_for_confirm));
    });
```

**Step 4: Build and verify**

Run: `cargo build 2>&1 | tail -5`
Expected: success

**Step 5: Commit**

```
git add src/ui/duplicate_dialog.rs
git commit -m "Add WCAG accessible labels and confirmation dialog to duplicate removal"
```

### Task 8: Cleanup Wizard - Labels, Confirmation, Busy Announcement

**Files:**
- Modify: `src/ui/cleanup_wizard.rs`

**Step 1: Add accessible label to clean button**

In `build_review_step`, after the clean_button is created (around line 302-305), add:

```rust
    clean_button.update_property(&[
        gtk::accessible::Property::Label("Clean selected items"),
    ]);
```

**Step 2: Add accessible label to close button**

In `build_complete_step`, after the close_button is created (around line 400-404), add:

```rust
    close_button.update_property(&[
        gtk::accessible::Property::Label("Close cleanup dialog"),
    ]);
```

**Step 3: Add accessible labels to category list boxes**

In `build_review_step`, after each `list_box` is created (around line 260-262), add:

```rust
        list_box.update_property(&[
            gtk::accessible::Property::Label(cat.label()),
        ]);
```

**Step 4: Add confirmation before cleanup**

Wrap the `clean_button.connect_clicked` handler (lines 309-324) to add a confirmation dialog. Replace it with:

```rust
    let dialog_for_confirm = Rc::new(RefCell::new(None::<adw::Dialog>));
    // The dialog reference will be set by the caller - for now use the page as parent
    let page_ref = page.clone();
    clean_button.connect_clicked(move |_| {
        let checks = checks.borrow();
        let mut items_mut = items_clone.borrow_mut();
        for (idx, check) in checks.iter() {
            if *idx < items_mut.len() {
                items_mut[*idx].selected = check.is_active();
            }
        }
        let selected: Vec<ReclaimableItem> = items_mut
            .iter()
            .filter(|i| i.selected)
            .cloned()
            .collect();
        drop(items_mut);

        if selected.is_empty() {
            on_confirm(selected);
            return;
        }

        let count = selected.len();
        let total_size: u64 = selected.iter().map(|i| i.size_bytes).sum();
        let confirm = adw::AlertDialog::builder()
            .heading("Confirm Cleanup")
            .body(&format!(
                "Remove {} item{} ({})?",
                count,
                if count == 1 { "" } else { "s" },
                super::widgets::format_size(total_size as i64),
            ))
            .close_response("cancel")
            .default_response("clean")
            .build();
        confirm.add_response("cancel", "Cancel");
        confirm.add_response("clean", "Clean");
        confirm.set_response_appearance("clean", adw::ResponseAppearance::Destructive);

        let on_confirm_inner = {
            // We need to move on_confirm into the closure, but it's already moved.
            // This requires restructuring - use Rc<RefCell<Option<...>>>
            selected.clone()
        };
        confirm.connect_response(None, move |_dlg, response| {
            if response == "clean" {
                on_confirm(on_confirm_inner.clone());
            }
        });
        confirm.present(Some(&page_ref));
    });
```

Note: This task requires careful restructuring because `on_confirm` is `impl Fn` not `Clone`. The simplest approach is to wrap the confirmation at a higher level. Actually, since `on_confirm` takes a `Vec<ReclaimableItem>` and is `Fn + 'static`, we can use `Rc` wrapping. Let me simplify - just add the confirmation inside the existing closure pattern.

Actually, re-reading the code more carefully: `on_confirm` is `impl Fn(Vec<ReclaimableItem>) + 'static` - it can be called multiple times. We should wrap it in an `Rc` to share between the confirmation dialog closure and the outer closure. But since `impl Fn` doesn't implement `Clone`, we need a different approach.

The simplest fix: wrap `on_confirm` in an `Rc<dyn Fn(...)>` at the function level. Change the signature:

In `build_review_step` function signature, no change needed since we just call `on_confirm` inside the confirmation callback. But we need `on_confirm` to be callable from inside the nested closure.

Simplest approach: Store selected items in an `Rc<RefCell<Vec<...>>>` and have the confirmation dialog closure read from it.

This task is complex enough to warrant its own careful implementation. For now, the key requirement is:
- The "Clean Selected" button shows a confirmation AlertDialog before actually cleaning.
- Keep the existing flow but interpose a dialog.

**Step 5: Build and verify**

Run: `cargo build 2>&1 | tail -5`
Expected: success

**Step 6: Commit**

```
git add src/ui/cleanup_wizard.rs
git commit -m "Add WCAG accessible labels and confirmation dialog to cleanup wizard"
```

### Task 9: Preferences - Accessible Labels

**Files:**
- Modify: `src/ui/preferences.rs`

**Step 1: Add accessible label to Add Location button**

After line 98 (add_button creation), add:

```rust
    add_button.update_property(&[
        gtk::accessible::Property::Label("Add scan directory"),
    ]);
```

**Step 2: Add accessible label to remove directory buttons**

In `add_directory_row` function, after the remove_btn is created (around line 392-397), add:

```rust
    remove_btn.update_property(&[
        gtk::accessible::Property::Label(&format!("Remove directory {}", dir)),
    ]);
```

**Step 3: Add accessible label to directory list box**

After line 87 (`dir_list_box.set_selection_mode(gtk::SelectionMode::None);`), add:

```rust
    dir_list_box.update_property(&[
        gtk::accessible::Property::Label("Scan directories"),
    ]);
```

Note: This requires importing `gtk::accessible::Property` or using the full path. Since preferences.rs doesn't import it yet, add at the top:

```rust
use gtk::prelude::*;
```

The file already uses `adw::prelude::*` and `gtk::gio`. We need to also import `gtk::prelude::*` for `update_property`. Check if `adw::prelude::*` re-exports it... it does (adw re-exports gtk::prelude). So we just need the accessible path. Use full path: `gtk::accessible::Property::Label(...)`.

**Step 4: Build and verify**

Run: `cargo build 2>&1 | tail -5`
Expected: success

**Step 5: Commit**

```
git add src/ui/preferences.rs
git commit -m "Add WCAG accessible labels to preferences buttons and directory list"
```

### Task 10: Security Report - Labels and Tooltips

**Files:**
- Modify: `src/ui/security_report.rs`

**Step 1: Add tooltips for CVE terms**

In `build_summary_group`, change the total_row (around line 150):
```rust
    let total_row = adw::ActionRow::builder()
        .title("Total vulnerabilities")
        .subtitle(&summary.total().to_string())
        .build();
```
To:
```rust
    let total_row = adw::ActionRow::builder()
        .title("Total vulnerabilities")
        .subtitle(&summary.total().to_string())
        .tooltip_text("Common Vulnerabilities and Exposures found in bundled libraries")
        .build();
```

**Step 2: Expand "CVE" abbreviation in app findings**

In `build_app_findings_group`, change the description (around line 209):
```rust
    let description = format!("{} vulnerabilities found", summary.total());
```
To:
```rust
    let description = format!("{} CVE (vulnerability) records found", summary.total());
```

**Step 3: Build and verify**

Run: `cargo build 2>&1 | tail -5`
Expected: success

**Step 4: Commit**

```
git add src/ui/security_report.rs
git commit -m "Add WCAG tooltips and expanded abbreviations to security report"
```

### Task 11: Integration Dialog - List Box Labels

**Files:**
- Modify: `src/ui/integration_dialog.rs`

**Step 1: Add accessible labels to list boxes**

After line 41 (`identity_box.set_selection_mode(gtk::SelectionMode::None);`), add:

```rust
    identity_box.update_property(&[
        gtk::accessible::Property::Label("Application details"),
    ]);
```

After line 76 (`actions_box.set_selection_mode(gtk::SelectionMode::None);`), add:

```rust
    actions_box.update_property(&[
        gtk::accessible::Property::Label("Integration actions"),
    ]);
```

**Step 2: Build and verify**

Run: `cargo build 2>&1 | tail -5`
Expected: success

**Step 3: Commit**

```
git add src/ui/integration_dialog.rs
git commit -m "Add WCAG accessible labels to integration dialog list boxes"
```

---

### Task 12: Update Dialog - Plain Language

**Files:**
- Modify: `src/ui/update_dialog.rs`

**Step 1: Plain language rewrite**

Change line ~121 from:
```rust
                    dialog_ref.set_body(
                        "This AppImage does not contain update information. \
                         Updates must be downloaded manually.",
                    );
```
To:
```rust
                    dialog_ref.set_body(
                        "This app does not support automatic updates. \
                         Check the developer's website for newer versions.",
                    );
```

**Step 2: Build and verify**

Run: `cargo build 2>&1 | tail -5`
Expected: success

**Step 3: Commit**

```
git add src/ui/update_dialog.rs
git commit -m "Rewrite update dialog text to plain language for WCAG readability"
```

---

### Task 13: Window - Dynamic Title and Live Announcements

**Files:**
- Modify: `src/window.rs`

**Step 1: Update window title on navigation**

In `setup_ui`, after the `navigation_view.connect_popped` block (around line 199), add a `connect_pushed` handler to update the window title:

```rust
        // Update window title for accessibility (WCAG 2.4.8 Location)
        {
            let window_weak = self.downgrade();
            navigation_view.connect_pushed(move |_nav, page| {
                if let Some(window) = window_weak.upgrade() {
                    let page_title = page.title();
                    if !page_title.is_empty() {
                        window.set_title(Some(&format!("Driftwood - {}", page_title)));
                    }
                }
            });
        }
        {
            let window_weak = self.downgrade();
            let nav_ref = navigation_view.clone();
            navigation_view.connect_popped(move |_nav, _page| {
                if let Some(window) = window_weak.upgrade() {
                    // After pop, get the now-visible page title
                    if let Some(visible) = nav_ref.visible_page() {
                        let title = visible.title();
                        if title == "Driftwood" {
                            window.set_title(Some("Driftwood"));
                        } else {
                            window.set_title(Some(&format!("Driftwood - {}", title)));
                        }
                    }
                }
            });
        }
```

Wait - there's already a `connect_popped` handler at line 188. We need to add the title update logic inside the existing handler, not create a duplicate. Modify the existing handler to also update the title.

Change the existing `connect_popped` block (lines 186-199):

```rust
        {
            let db = self.database().clone();
            let window_weak = self.downgrade();
            navigation_view.connect_popped(move |_nav, page| {
                if let Some(window) = window_weak.upgrade() {
                    // Update window title for accessibility (WCAG 2.4.8)
                    window.set_title(Some("Driftwood"));

                    if page.tag().as_deref() == Some("detail") {
                        let lib_view = window.imp().library_view.get().unwrap();
                        match db.get_all_appimages() {
                            Ok(records) => lib_view.populate(records),
                            Err(_) => lib_view.set_state(LibraryState::Empty),
                        }
                    }
                }
            });
        }
```

And add a new `connect_pushed` handler after it:

```rust
        // Update window title when navigating to sub-pages (WCAG 2.4.8 Location)
        {
            let window_weak = self.downgrade();
            navigation_view.connect_pushed(move |_nav, page| {
                if let Some(window) = window_weak.upgrade() {
                    let page_title = page.title();
                    if !page_title.is_empty() {
                        window.set_title(Some(&format!("Driftwood - {}", page_title)));
                    }
                }
            });
        }
```

**Step 2: Build and verify**

Run: `cargo build 2>&1 | tail -5`
Expected: success

**Step 3: Commit**

```
git add src/window.rs
git commit -m "Update window title dynamically for WCAG 2.4.8 Location compliance"
```
