/* ═══════════════════════════════════════════════════════════════════════════
   Curio account site: the whole design system.

   One file, no dependencies. Dark is the default (the app's own character),
   with a light mode that follows the operating system. Every surface is a
   glass panel over an aurora backdrop, and motion is decorative only: the
   reduced-motion block at the end turns all of it off.

   No inline styles are used anywhere on the site (the CSP forbids them), so
   anything a script needs to change goes through classes or CSSOM.
