/*
 * The shared theme for gentoo and corduroy.
 *
 * This file is byte-identical in both sites (gentoo: core/static/css/styles.css, corduroy: the
 * same path). Edit both or neither -- gentoo's test_theme.py checks. Site-specific rules go in
 * gentoo.css / corduroy.css, which are loaded after this and consume the tokens defined here.
 *
 * Bootstrap 5.3 underneath. The look is done by redefining Bootstrap's own CSS variables under
 * the class names the templates already use, so a template that says `thead.table-dark` or
 * `badge bg-warning` keeps saying it and simply renders in the new style. Where Bootstrap
 * compiles a value into a rule rather than a variable (form focus, checkbox checked, font
 * sizes on inputs) the rule is overridden directly, and says so.
 *
 * Tokens. Bootstrap's `--bs-*` are redefined where the theme disagrees; the few app tokens are
 * prefixed with nothing and listed under "App tokens". Dark mode is `[data-bs-theme="dark"]`
 * on <html>, set by js/theme.js before the first paint.
