/* ==========================================================================
   Vincennes Worship Team — polish.css
   Borders · radii · shadows · focus · states · motion
   Load LAST (after style.css). Pure CSS; optional JS hooks are documented in
   /workspace/worship-app-design/POLISH-NOTES.md. Everything degrades
   gracefully if a hook is missing.
   Rules of the road:
     • animate transform / opacity (and the individual `scale` property) only;
       paint-only properties (color, background, box-shadow) get short fades.
     • press feedback uses the `scale` property so it never clobbers a
       component's own `transform` (e.g. .pw button, inline drag transforms).
     • entrance animations use fill-mode `backwards`, so nothing lingers after
       they finish (important for the drag-reorder inline transform).
