/* ============================================================================
   DraftADay — documentation site.

   Layout only. Every colour here is a token declared in /styles.css, which is
   loaded first: --paper/--dawn/--card surfaces, --ink/--ink-2/--mist/--blue/
   --amber-2 text (each measured >= 4.5:1 on every surface it sits on, in both
   schemes), and --band/--band-fg-2 for code. Dark mode therefore arrives with
   the tokens, through prefers-color-scheme, with nothing to keep in sync here.

   Verified at 1280, 768 and 360 CSS pixels. Below 820 the left nav becomes a
   drawer behind a Menu button and the in-page contents collapse.
