/* ============================================================
 * Decima design tokens
 * ============================================================
 * Warm monochrome, five neutrals, no chroma in the brand palette.
 * Usage ratio roughly bone 60 / ink 30 / everything else 10.
 *
 * Contrast rules (checked by scripts/check-brand-contrast.js):
 *   - Body text: ink or graphite on bone only.
 *   - Slate is for borders, dividers and large display type only.
 *     Slate on bone is ~3:1 and fails WCAG AA for normal text.
 *   - State colours are for status only, never decoration, and only
 *     on bone (state-ok on mist is 4.0:1 and fails AA).
 *   - Every status also carries a text label or icon. Never encode
 *     meaning in colour alone.
 *
 * Fonts are self-hosted from /fonts (SIL OFL, licences alongside).
 * Never load them from the Google Fonts CDN at runtime.
