/* event-docs.css — shared design system for the kaldamus entity-reference docs
   (docs.html + event-*.html). Dark "Liquid Glass" theme, deliberately mirroring
   the real app's own tokens in ui/public/css/style.css (--bg-primary, --accent-blue,
   --accent-gold, glass surfaces) rather than the light slide-deck palette used by
   deck.css. One deliberate dark theme only, no light-mode variant — same posture
   as the app itself. Pair with event-docs.js for the Mermaid CDN loader, which
   reads its palette live from the custom properties below.

   Page format is fixed — see docs/HTML_DOC_STANDARD.md and the DOC STANDARD
   components at the foot of this file. */
