   The shared rating and private feedback component. Loaded only
   on pages that render it, which is every genuine tool page.

   NO NEW PALETTE. Every colour resolves to an A-to-Z token with
   the same fallback value after it, so load order cannot break
   it and nothing here introduces a second design system.

   STATE IS NEVER COLOUR ALONE. A selected star is filled AND
   larger AND named in the text beneath; an error is coral AND
   says what is wrong; success is mint AND says thank you.
