   COLOUR OWNERSHIP (Constitution Article 5, FEAT-PccTheme-02)
   ------------------------------------------------------------
   --brand-primary / --brand-secondary / --brand-accent are NOT
   declared here. They are injected into :root by _Host.cshtml,
   resolved from site-profile.yaml -> SiteSettings -> constant and
   validated as hex literals (BRULE-BrandToken-01).

   Everything blue below is DERIVED from those three with
   color-mix(), so changing the site's brand colour re-tints the
   whole page coherently without touching this file. The fallbacks
   in the var() calls exist only so the stylesheet is still legible
   if opened standalone — at runtime the injected values always win.

   Neutrals (white, greys, ink, hairlines) are deliberately static:
   they are not brand, and making them settable would let an
   operator render the site unreadable.
