/**
 * The design tokens (milestone 23, ruling 2).
 *
 * Values are the Tailwind 4 zinc/blue/red ramps the app rendered before the
 * StyleX conversion, carried over verbatim so the palette does not shift.
 * Each token holds its dark value under `prefers-color-scheme: dark` — the
 * same media strategy Tailwind 4 defaulted to. There is no theme toggle and
 * no `data-theme` attribute; the scheme follows the operating system.
 *
 * Name tokens by role, never by shade: a call site asks for `border`, not for
 * zinc-200.
