/* ═══════════════════════════════════════════════════════════════════════════
   Developer Reference — standalone docs chrome
   ───────────────────────────────────────────────────────────────────────────
   Serves /developer/reference/<slug>. This page deliberately does NOT extend
   base.html: the dashboard shell (fixed 280px sidebar + navbar) left roughly
   half the viewport for a three-column reference, which is the whole reason
   the previous docs page felt cramped.

   Self-contained by design — it does not read theme-tokens.css, so the page
   renders identically whether or not the portal CSS is present. Dark mode is
   driven by the same [data-theme="dark"] attribute the rest of the site sets,
   so the user's choice carries across.

   Prefix: everything is --dr- / .dr-.
