/**
 * Queue wait + progress banner — design tokens, no hardcoded colors.
 *
 * Phase 2.4 of the standalone Coordinated Pool Operations plan
 * (May 7, 2026). The banner appears at the top of the FPS calculator
 * page when a user submits a task that creates a pool job. Polls
 * /queue/status every 2 s and renders queued/running/failed states.
 *
 * Dark mode: PCBuildMate's theme tokens already invert when
 * `html.dark` is set; this CSS uses those tokens so we get dark mode
 * for free. Mobile/zoom: clamp() on font-size + responsive padding.
 *
 * Local custom-property scope (--qwb-*) lets per-state cards override
 * accent color without touching the theme palette.
