 * Design system for the dark header/footer chrome + homepage sections,
 * matching the provided mockup exactly (docs/PROJECT_GUIDE_V2.md /
 * template-parts/UI_Design/elempresarioia_frontpage_UI.png). Scoped to
 * its own --uiv2- variable namespace and unprefixed component classes
 * (.site-header, .hero, .tool-card, etc.) rather than reusing the
 * existing --epia- tokens, since this is a deliberately distinct,
 * fixed-palette system (dark chrome, light homepage body) rather than
 * an extension of the site-wide light/dark toggle built in Milestone 2.
