/**
 * backroom.css — The Backroom volunteer enrollment page.
 *
 * Ported from the approved standalone mockup (backroom-mockup.html).
 * Standalone-only bits dropped: html/body/html resets, ::selection, :focus-visible
 * global, .site-header, .site-nav, .kit-theme-toggle, .site-footer, .skip-link.
 * Those all live in the theme's existing frontend.css / global styles.
 *
 * Token map: the Backroom's --c-* palette is DEFINED below on .backroom-page,
 * mapped onto the theme's --wp--preset--color--* variables (set in theme.json
 * for dark and flipped in frontend.css on html[data-theme="light"] body). This
 * makes the whole page (text, hero, roles index, and the custom dropdown)
 * follow the site's light/dark toggle. The gold accent is held per theme
 * because the theme's preset accent is an off-white placeholder in dark mode,
 * while the Backroom design is gold in both themes.
