/*
 * The admin base stylesheet (milestones B1 and B4).
 *
 * BootstrapBlazor's stylesheet (bootstrapblazor.min.css 20.1.3) did not only style its own
 * components: it also restyled plain elements and Bootstrap/Theme.Base classes on every admin
 * page - check boxes, links, disabled controls, tables, list groups, pagination, popovers,
 * modals, toasts. FrameworkSiteInfo links this file in that sheet's place - before the theme's
 * sheet, exactly where BootstrapBlazor's was - on every document of the theme: the Vue admin
 * shell (milestone B1), the downstream Razor admin pages on _AdminLayout and every public page
 * (milestone B4; the Fluid theme's _Head partial links it the same way). No page links
 * BootstrapBlazor's sheet any more; the Tailwind theme links neither.
 *
 * What is here: the declarations of BootstrapBlazor's sheet whose selector needs no
 * BootstrapBlazor-only class and that were in effect on the admin - the ones Theme.Base's
 * compiled CSS and /api/themes/admin-variables.css did not override for the same element - under
 * Atheox variable names. Rules that only served BootstrapBlazor components, rules for markup no
 * admin page renders and declarations without a visible effect are not carried over.
 *
 * Cascade. The selectors are BootstrapBlazor's and the file sits where its sheet sat, so every
 * tie resolves as it did: the theme, linked after this file, wins wherever it states the same
 * property with equal or higher specificity (for example Bootstrap's `.row > *` gutter on a
 * `.col-* .form-check`), and these rules win where BootstrapBlazor's did.
 *
 * Colours. BootstrapBlazor's literal colours follow the theme instead (owner decision 2026-10-06):
 * the hover border is the accent tinted half towards white (Bootstrap's focus-border tint), the
 * check box focus border the tertiary text colour, the dark dropdown surface the neutral ramp's
 * 700 step. A named accent is written onto <body>, so the hover border is resolved there too.
