/* ── palette candidates ──────────────────────────────────────────────────
   Five alternatives to the shipped Pricempire navy, so the look can be judged
   side by side instead of argued about. Each is a full override of the token
   set site.css declares on :root — NOT a tweak of two colours, because a
   half-swapped ladder is what makes a palette look broken rather than
   different.

   `node site/xf-contrast.mjs` re-reads this file and runs every text/surface
   pair in every block below through WCAG AA. A palette that does not clear
   4.5:1 does not ship — that check is the reason these can be swapped without
   a design review each time.

   To try one: the palette button in the header. It writes
   document.documentElement.dataset.theme and remembers the choice per browser.
   Removing a block here removes the option; the shipped :root is unaffected. */
