/* Keep 1031 platform -- one stylesheet for the console and the portal.
 *
 * BRAND: navy and gold, ring mark. Operator ruling 2026-08-13.
 *
 * EVERY COLOUR BELOW COMES FROM assets/brand/keep1031-tokens.css, which is
 * byte-identical to keep1031-ops/assets/brand/keep1031-tokens.css. The pack is
 * the palette; this file maps it onto local names and does the layout.
 *
 * The suite enforces both halves: no hex may appear here that is not in the
 * pack, and the pack must match the ops repo's copy. That is the whole
 * mechanism by which campaign mail and the product cannot drift apart -- which
 * they already had, silently, before the ruling. A colour is not the kind of
 * thing that fails a test on its own.
 *
 * SO: to change a colour, change it in BOTH copies of the pack and then here.
 * Adding a new one here without adding it to the pack fails the suite, which
 * is the intended amount of friction: an invented colour is how a second
 * palette starts.
 *
 * Colours are defined once on :root and only re-bound under the dark blocks,
 * so a token can never be defined solely inside a media query.
