/*
 * Uniden Mobile theme — shared shell stylesheet. PRACBILL-1717, PRACBILL-1853.
 *
 * Mobile first. Everything outside a media query is the 390px layout; the
 * `min-width: 768px` block at the bottom is the only desktop enhancement.
 *
 * NO COLOUR LITERALS. Every UI colour resolves through a CSS custom property
 * declared in theme_config.php's `theme_options` block, which is the single
 * source of the theme's defaults — theme.tpl emits them as {$themeDefaultsCss}
 * and a site's saved overrides as {$themeOptionsCss}. Adding a hex here would
 * create a second, silently-diverging source of truth and make the colour
 * unreachable from Website Information. The only colour data in the theme
 * lives inside img/*.svg, which is immutable brand artwork.
 *
 * Available properties:
 *   --brand-50/100/300/500/600/700/900  derived from the brand_500 option
 *   --link  --ink-900  --ink-500  --border  --canvas  --paper
 *   --font-display  --font-body  --font-mono
 *   --radius-control  --radius-card       from the corners option
