Show how theme and layout tokens flow to components. Readers change the radius, spacer, or primary color and see the button, input, alert, and card update together. The Remint control demonstrates how derived tokens (bg-subtle, fg, border) restate the theme today.
Rebuild $theme-colors through a new theme-color() helper so every pairing
(fg, bg-subtle, border, focus-ring, …) derives from var(--{name}-base) with
color-mix, instead of pointing at fixed palette stops. Add color-stop() and
theme-blend() in _colors.scss and theme-pair() in _theme.scss to replay the
palette recipe against the base. Default compiled colors are unchanged.
One :root override of --bs-{name}-base now re-mints the whole set. Add a
Root option to the token playground to demonstrate this, and document the
mechanism, the cascade scope limits, and single-token overrides in theme.mdx.

Stacked on #42929. Review and merge that first; this builds on it.

Default compiled colors are unchanged (exact parity).:root { --bs-primary-base: … }override now re-mints the whole set. Add a Root option to the token playground to show this next to Base and All.:root-vs-subtree cascade limit, and single-token overrides incustomize/theme.mdx.Note: reminting from one variable works at
:root. For a subtree, CSS resolves the derived tokens where they are declared, so users restate the tints/shades they need.Supersedes the hardcoded pairings.
