/* ============================================================
   Help center (/help/) — additive styling on top of /styles/refresh.css.
   Reuses refresh.css tokens (--text, --muted, --accent, --panel,
   --panel-border, --radius-card, --shadow, --ui-font, ...) and the shared
   .sbb-legal shell/typography classes, same convention as blog.css and
   versus.css. Own namespaced classes (.sbb-help-*) rather than reusing
   .sbb-blog-* — each content section gets its own stylesheet, per the
   "reproduce, don't cross-import" convention documented in
   VersusLayout.astro's header. Only loaded on /help/, /help/topic/*, and
   /help/[slug]/. See KNOWLEDGE-BASE-SPEC.md section 3.3.
