 * skinned as the LUXWORK theme rather than a second design system.
 *
 * Palette source: docs/design/luxwork-site-structure.md, cross-checked against
 * the colours actually used in apps/lux (#0d1512 ground, #179c6b, amber).

 * ⚠ NEVER RED (standing ruling). Cautions are amber, and colour is never the
 *   only signal — every amber note also carries a word.
 * ⚠ No web fonts, no analytics, no third-party requests of any kind. The
