/* ================================================================ liquid glass
 * Used only on surfaces that float above content: chat header pills, composer, tab bar, pinned bar,
 * scroll-to-bottom, selection bar, menus, dialogs, sheets and toasts. Lists, settings pages and
 * message bubbles stay solid for readability. Three ingredients:
 *   tint      a translucent fill that adapts to light / dark;
 *   edge      a hairline rim plus a brighter top highlight (light catching the glass);
 *   depth     a soft two-layer shadow.
 * Menus, dialogs and sheets carry text you read, so they use the stronger, less transparent tint.
 * Without backdrop-filter support every surface falls back to its solid colour (end of section).
