/*
 * admin-settings.css — global styles for the Admin Settings page (/admin/settings).
 *
 * SCOPING: every rule is namespaced under `.admin-settings-page` — the root <div> of
 * AdminSettings.razor. This intentionally replaces Blazor CSS-isolation: the styles now
 * survive the page's markup being split into child components, because children render
 * inside the .admin-settings-page subtree and these descendant selectors keep matching.
 *
 * EXTENDING: as you fold new admin functions into AdminSettings, add their styles here
 * under `.admin-settings-page <your-class>`. Keep class names page-unique and rely on the
 * namespace — never use bare element/generic selectors (e.g. `.table`, `button`), which
 * would leak app-wide once de-scoped. Group new sections with a "═══ Title ═══" comment header.
 *
 * Linked in Pages/_Layout.cshtml after site.css. Hoisted verbatim from AdminSettings.razor.css
 * (AI-readability campaign, round seven) — pure transform: original rules + `.admin-settings-page` prefix.
