/* =====================================================================
   P0/P1 FOOTER. Root cause of the W15 defect: .footer-cta__title used var(--text-1) (#eef2fb, a dark-palette
   token) on the ivory .footer-band. The footer is now ONE light surface that re-scopes every palette token to a
   dark-on-light value, so anything inside it that inherits --text-*, --line-* or .btn colours stays readable.
   Measured contrast on #f4f6fa: ink 16.9:1, ink-2 10.2:1, ink-3 7.0:1, link 7.6:1 (qa/w16-check.mjs).
