/* Union UI -- wayfinding-inspired design system for FunAnanas's non-game
 * routes: the sign-in door (`/`, views/index.hbs) and the lobby concourse
 * (`/m`, `/m/industry`, `/m/wiggle` -- views/m.hbs, *-lobby.hbs). Named
 * after, and modelled on, Toronto Union Station's own wayfinding: light
 * theme is the Great Hall by day (limestone, brass), dark is the Concourse
 * at night (ink, glowing amber) -- same tokens, same meanings, different
 * light, the way the real building reads under two different exposures.
 *
 * Scope is enforced by `[data-shell="union"]`, on <body> (set from `shell`
 * in the page props -- see src/index.ts's pageProperties()) or on the <div>
 * that views/layouts/main.hbs wraps its header and drawers in. Every
 * selector below is scoped under that attribute, so this file loads
 * globally (same as phosphor-terminal.css and friends). A match page
 * (views/industry.hbs, wiggle.hbs) sets no shell on <body>: there only the
 * header and the two drawers are Union's, and the page under them keeps its
 * own look.
 *
 * Component classes use a `uu-` prefix, mirroring industry-terminal.css's
 * `ic-` convention. Structural spacing (flex/grid/gap) on the pages that use
 * these still comes from Tailwind utilities where available; this file
 * otherwise sets color, typography and border/shape. The public pages
 * (views/layouts/public.hbs) are laid out by their own `.uu-public-*`
 * classes below.
 */

/* Cinzel (display) and Overpass (body/UI) are self-hosted variable fonts,
 * converted to .woff the same way IBM Plex Mono/Sans already are (see
 * industry-terminal.css's header comment) -- one file covers the whole weight
 * range via `font-weight: <min> <max>` instead of one file per static
 * weight, since both ship as a single variable-font source. IBM Plex Mono
 * itself needs no new @font-face here -- fonts.css declares it and both
 * layouts load that, so it's simply reused for Union UI's tabular data
 * (lobby codes, player counts, timestamps).
