/* ============================================================
 * tiko-ui.css  -  Tiko Learn shared design system (plain CSS)
 * ------------------------------------------------------------
 * Used by index.html (learner hubs) and meant to be reused by the
 * SGBV module restyle and the master-trainer dashboards.
 * Link it BEFORE a page's own <style> so the page can override:
 *     <link rel="stylesheet" href="tiko-ui.css" />
 * Visual language: Plus Jakarta Sans, purple #702082 / dark #4A1556,
 * teal #1D9E75, gold #D97706; 2px bordered cards with a thicker bottom
 * edge ("duo" tactile buttons), gradient hero bars, glass tiles over a
 * purple gradient, 16-24px radii, bottom sheets with a handle.
 *
 * RULES OF THIS FILE
 *  - Everything is prefixed .tk- (no clash with page CSS).
 *  - Colours/radii come from CSS variables on :root (--tk-*). Every
 *    var() carries its light-theme fallback, so old Android WebViews
 *    without custom properties still render correctly.
 *  - No :has(), no gap (margins are used), no logical properties.
 *    Prefixed flex/transform where Android 4.4-6 needs it.
 *  - Dark mode: set <html data-theme="dark"> (or "light"). Following the
 *    OS is opt-in: add class "tk-auto-theme" to <html>. (index.html is
 *    light-only, so it does not opt in.)
 *  - RTL: set dir="rtl"; the few directional rules have [dir=rtl] twins.
 *
 * COMPONENTS (modifiers in brackets)
 *  .tk-hero       gradient hero bar            [--teal --gold --coral --dark]
