 * Source of truth: /foundation/index.html (foundation v0.3, May 2026).
 *
 * Every page in terminal/ must load this file BEFORE any per-page styles.
 * No off-brand hex codes allowed in this file. The audit (2026-05-20)
 * flagged 185+ stray off-brand colors across 11 pages + 4 overlays —
 * this module is the single source of truth that ends that drift.
 *
 * Forbidden hex (never re-introduce — listed in foundation.js OFFENDERS):
 *   legacy GitHub dark surfaces (0d, 16, 21 ramps)
 *   GitHub blues (58, 79, 1f ramps)
 *   GitHub greens, reds, yellows
 *   off-brand orange, pink, purple
 * See terminal/shared/foundation.js for the literal list.
