/* RestorSignal docs surface (docs.restorsignal.com).
   Palette/tokens and topbar/header/footer chrome are ported verbatim from
   public/landing/style.css to keep one visual identity across origins (no shared file
   to @import across subdomains, so the tokens are duplicated here on purpose).
   Article typography favors readability over the landing page's marketing display type —
   long-form technical docs, not a hero section (project prompt §16: "la priorité reste
   la lecture"). */
