   Theme Service — components.css (finalized). Class-based component styles,
   written purely against tokens. Opt-in: add these classes to your markup and
   they pick up whatever theme is active (theme.css). Every interactive element
   defines default / hover / active / focus-visible / disabled / expanded states.
   Motion is gated through --motion so the "disable animations" hook and OS
   reduced-motion both fully stop it (see effects.css).
