/* =============================================================================
   Guide article — public help-center article chrome.

   Ported from the "Guide.html" design handoff (Claude Design). Every selector
   is namespaced with the gd- prefix and scoped under .guide-doc so it never
   collides with the global site.css rules. The marketing nav + footer are NOT
   defined here — public pages already get TopBar + FooterComponent from
   MainLayout, so this file owns only the hero + article body + TOC + related.

   Backing the design tokens with the app's existing --icu-* / --hermes--*
   variables where a clean match exists, with literal fallbacks so the article
   renders identically even if a token is missing.
