 * css/app.css — All styles. Plain CSS, no preprocessor.
 *  - :root holds design tokens (colours, radius, fonts). Dark mode overrides
 *    them under :root[data-theme="dark"] and under prefers-color-scheme: dark
 *    when the user has not forced light. Use the variables, not raw colours.
 *  - Rule colours are NOT here: ayah.js generates the .g-<group> { --c } rules
 *    from js/data/rules.js. Components use var(--c).
 *  - The page is RTL (dir="rtl" on <html>), so "start" is the right side.
 *  - Sections below follow the page order: layout, components, home, chapter,
 *    ayah, legend, sheet, quiz/practice, glossary/search, settings, diagram.
