/* ==========================================================================
   Quarto Ink "Atelier" UI layer
   Paper and ink: the interface itself looks annotated (hand-drawn circle on
   the active tool, ink-drop colour swatches, index-card slide navigator,
   ruler-style slide scrubber, stamp-style mode badge).

   Loaded after the base styles in index.html. It restyles existing elements
   and keeps every id, class and data attribute the app logic depends on.
   Layout-critical rules (pointer-events, dock flex directions, Excalidraw
   panel geometry) are intentionally left to the base stylesheet.
