  /* Brand: Blythe Driveways "Tarmac and high-vis" (re-locked 2026-07-29 after
   * the A/B/C colour spread; supersedes the sandstone accent, Hugh picked A).
   * Deep slate-ink ground, stone off-white paper, one burnt-orange accent.
   * Clear of our other forks (blues and golden ambers) and of the Solihull
   * SERP field (green twice, dark red once). See DESIGN-VISION.md.
   *
   * IMPORTANT: --color-secondary is a brand accent only, use it for FILLS
   * (button backgrounds, decorative bars, icon backgrounds), NEVER as text on
   * white or dark backgrounds. The orange fill carries the warm-white
   * --color-secondary-fg. --color-accent is fill-only under the same rule.
   * Run `npm run check` to validate contrast after any token override.
