a11y: bring UI to WCAG 2.2 AAA compliance

Browse Source 
Semantic HTML: lang attr, landmarks (header/main/region/complementary),
heading hierarchy (h1-h3), dl/dt/dd for info panel.

ARIA: labels on all icon buttons, aria-hidden on decorative icons,
progressbar role with dynamic aria-valuenow, aria-haspopup/expanded
on all menu triggers, role=listbox/option on playlist, aria-selected,
computed aria-labels on playlist rows.

Contrast: raised --textMuted/--textDim/--icon to AAA 7:1 ratios.

Focus: global :focus-visible outline, slider thumb glow, menu item
highlight, switch focus-within, row focus styles.

Target sizes: 44x44 hit areas on zoom/window/remove buttons via
::before pseudo-elements.

Keyboard: playlist arrow nav + Enter/Space activate + Alt+Arrow
reorder with live region announcements + move buttons. Speed menu,
subtitles menu, and recent menu all keyboard-navigable with
Arrow/Enter/Space/Escape. Dividers resizable via Arrow keys.

Dynamic document.title updates on video/folder load.
