/* ==========================================================================
   Cookie consent banner — partials/consent.html, behaviour in js/track.js
   Not in the Figma file (added 2026-10-08). Everything here is a token or a
   type style the site already has: page ground, the 3 px Rich Black 1 rule,
   the Amber 4 action and ring, 15 px type, the 25 / 50 spacing steps.

   Desktop: copy left, three buttons right; the settings panel opens below
   across the full working area. Phone: one column, buttons share a row.

   The banner sits outside .page, so base.css's z-index pin (`.page > *` at
   1, specificity 0,4,0) does not reach it and a plain number is enough.
