/* Guide panel — docs edition (Phase 2b-2 v1).
 *
 * The app styles this panel with its Tailwind pm-* palette. mkdocs-material has neither Tailwind
 * nor that palette, so the panel needs its own CSS here. It is written against MATERIAL'S OWN
 * custom properties (--md-*) rather than hard-coded colours, so the panel follows the site's
 * theme — including any palette switch — instead of fighting it.
 *
 * Everything is scoped under #guide-panel / .guide-fab. Nothing defines a bare generic class at
 * document level: a rule like `.block { display:block }` would leak into material's own markup.
 * The one exception is intentional and tightly scoped: `#guide-panel.hidden`, because guide.js
 * toggles the literal class name "hidden" via classList and that contract cannot be renamed here.
