/*
 * Pages of passkey-access. The app sets its look by overriding the --access-* variables in /access-theme.css.
 *
 * Dark values apply with a dark device, or with "dark" as the app's colour scheme (js/theme.mjs sets data-access-theme
 * on the root element: light, dark, or auto for the device). :where() keeps these rules as weak as a plain :root, so
 * the app's access-theme.css, loaded after this file, wins in both modes.
