 * design.css — global design tokens for the new design system.

 * Tokens are namespaced with `--d-` to coexist with legacy `--bg`, `--ink`,
 * `--lime`, etc. that the screens still use. As each screen is ported
 * (tasks #3-#12), its local vars get replaced with `--d-*` and the legacy
 * definitions are removed.
