/* Shared alert/toast/confirm framework styling — paired with ui-alerts.js. Include
   both on every page (see the <link>/<script> pair near the end of <head> on any
   page) instead of using window.alert/confirm/prompt or a one-off inline message
   box, so every notification and confirmation in the app looks and behaves the same
   way. Self-contained --ui-* tokens (not borrowed from shell.css or the marketing
   pages' own design tokens, since not every page defines those) so this renders
   identically everywhere it's used; still respects OS dark mode. */
