/* ============================================================
   AI Auto-organize / Auto-file  (js/autofile.js)
   ------------------------------------------------------------
   A non-intrusive right-side suggestions panel + a subtle
   "Organize" affordance pill. Theme-aware: every colour comes
   from style.css custom properties that flip in dark mode.
   All classes are `af-` prefixed. Sits above the page content
   but below modals/search (z ~700 vs modals ~500? — no scrim,
   so it never blocks the page). Uses 720 to clear sidebars.
