/*
 * notes-workbench.css — the /notes/ workbench.

 * Every rule is scoped under #notes-workbench (or the .nw-page wrapper), which
 * is the house convention here — see assets/css/quest-idea-portal.css.
 *
 * The site is pinned dark by assets/js/user-overrides.js, so there are no
 * prefers-color-scheme rules: colors come from the theme's tokens
 * (--bs-* and --zer0-*) and inherit the reader's chosen accent for free.
 * color-mix() always follows a flat fallback declaration.
