/* Trash Talk Tour — ZeroWaste.Org 3.0 cut
   Scoped under .tt-root so tokens never leak into the rest of the site.

   The 3.0 kit's own token NAMES (--zw-blue, --radius-lg, --measure…) are
   deliberately not reused here. Custom properties inherit, this stylesheet is
   unlayered, and unlayered CSS outranks Tailwind v4's `@layer theme` — so
   `.tt-root { --radius-lg: 14px }` would silently reset the radius scale for
   every `rounded-lg` utility inside the tour's pages, and the tour's *events*
   page renders shared Tailwind-styled partials under this same body class.
   That is the bug test/assets/brand_tokens_radius_test.rb exists to prevent.
   The kit's VALUES are adopted; its names stay out of the cascade. */
