/* =====================================================================
   Culinow SEO Bundle Builder — design tokens, reset and component classes.

   Hand-ported from the original application's tailwind.config.ts palette and
   the @layer components block in src/app/globals.css, so colours, radii,
   shadows and control sizing match the original interface exactly. No build
   step and no framework: this is the compiled result, written by hand.
