/* =========================================================================
   Shared Help modal styling (paired with /scripts/helpModal.js).
   Self-contained: relies only on the GRAIPH design tokens in /graiph-tokens.css
   (loaded by every interface), so it themes light/dark automatically.
   Ported from the Field Describer help (public/field/styles/overlays.css),
   rebranded from .fd-* to neutral .help-* classes for cross-interface reuse.
