/* Pack and Kin Studio — the shared skin for every PUBLIC (anonymous) page.
   Home, pricing, sign-up, dealer program, legal, login and the error pages all
   link this one file.

   WHY IT EXISTS. The dark gradient this replaces was hand-copied into nine
   templates, so every palette change was a nine-file sweep that nothing
   enforced — and the marketing pages had drifted onto a palette that appears
   nowhere in static/brand/tokens.css, the file that calls itself the source of
   truth. This restores the real brand: cream ground, navy ink, gold and red.

   NO JAVASCRIPT is needed by anything styled here, and none should be added.
   config/test_csp_nonce_coverage.py holds inline scripts and on*= handlers at a
   hard zero; disclosure widgets use <details>/<summary> for that reason.

   Colours are the tokens from static/brand/tokens.css (source of truth:
   core/branding.py), re-declared rather than imported so a public page is one
   request and cannot render unstyled while a second file is in flight. */
