/* ==========================================================================
   base.css — Honolulu Blue System (base layer)

   This file rarely changes. It defines the constants of the brand:
   the core palette, type stack, spacing scale, and radii.

   Per-app tweaks (a warmer gray, a different accent tone, etc.) belong in
   an override file in /overrides, loaded AFTER this one. Never edit the
   values below directly for a single app — that turns this into another
   one-off file instead of a system.
