/* ─────────────────────────────────────────────────────────────
   SNACKS SLIDES — presentation deck framework.

   SOURCE OF TRUTH: snacks-labs/packages/slides-core/assets/.
   Copies in apps/slides-web/public and in snacks-www (js/, css/)
   are written by `npm run sync:engine -w @snacks-labs/slides-core`.
   Edit there, then sync; edits to a copy will be overwritten.

   Usage: mark up <main data-snacks-slides> whose direct children
   are the slides, include this stylesheet and /js/snacks-slides.js.
   Everything else (HUD arrows, minimap, progress, present mode,
   blackout, deep links, print) is injected by the script.

   Theming: reads the page's tokens when present, with fallbacks:
     --red, --bg, --fg, --rule, --ddc, --body
   Page hooks:
     [data-title="..."]              slide title (minimap hover chip)
     [data-slides-hide-on-present]   hidden while presenting
