/* ============================================================
   Blackburn Legacy — public pages (sign in, create account, reset)
   Version 2026-09-15. Loads AFTER assets/css/heirloom.css and uses its
   tokens, so these pages carry the Branch B brand colours: ink-navy,
   antique gold, brass and parchment. Night mode follows the same
   localStorage key the member pages use (la-theme = 'night').
   No external icon font: every icon is inline SVG.
