   avatar tools - site stylesheet
   Three-column wiki layout: sidebar (collapsible) | content | TOC rail.
   Restrained palette: one accent (cyan) for emphasis, the rest neutral.
   No animations beyond short transitions, no gradients.

   THEMING
   -------
   Every colour is a token on :root. The dark palette is the default; the
   light palette is applied under `:root[data-theme="light"]` (the sidebar
   toggle, persisted in localStorage) and under `prefers-color-scheme:
   light` when no explicit choice is stored. Never hard-code a colour in a
   component rule: use the tokens, or `currentColor` inside inline SVG.

   SHARED COMPONENTS (reusable by any page, incl. the analyzer/viewer)
