/* developers.povito.com — Povito V2 (platform/packages/brand/docs/design.md), developer-console register.

   Light-first: Cloud White canvas, white surfaces, Midnight Navy chrome, Povito Purple for every action,
   Smile Coral as a deliberate highlight only. Dark is an explicit toggle (data-theme) on the console
   palette (§1.5). Logical properties throughout so `dir="rtl"` just works. Type: Plus Jakarta Sans,
   IBM Plex Sans Arabic for `ar`, JetBrains Mono for code. Docs body reads at 15/1.6 (a step above the
   marketplace's 14/1.5, for long-form reading); everything else is on the §2.1 scale.

   Every colour literal lives between @tokens and @end-tokens; the rules below only ever use var().
   Radius is the closed scale 6 · 8 · 10 · 12 · 16 · 20 · 9999 (§3). */
