   Builds ON TOP of ui.css tokens. All homepage classes are prefixed .hp-.
   New tokens are namespaced --hp-* (plus a controlled re-definition of the
   shared ui.css tokens inside the dark-mode block so existing components flip).
   No JS. Accordions = native <details>. Language switcher reuses lang.js.
