 * Dark palette switched 2026-05-08 from the navy mix to the gray
 * Discord-style scheme used in tmp/design/*-prototype.html. Reasoning:
 * the prototypes are the source-of-truth for visual design; navy didn't
 * match. Hex values are lifted verbatim from the prototypes.
 *
 * If a component had hardcoded the navy colors (rare — most use var()
 * tokens), those need follow-up audits. Search for #1a1a2e / #16213e /
 * #0f3460 / #1e2a4a hex strings and migrate to the new scheme.
