/*
 * Phase 6 — ported from ~/tv-channel-server/client/src/index.css, the
 * original Streaming Engine dashboard's own stylesheet, to preserve its
 * layout/visual identity (bento grid, cards, tiles, chart, sessions
 * table) inside the React Stream Engine page. Every selector is scoped
 * under .stream-engine-embed so it can never leak onto the rest of the
 * Bootstrap-based admin UI — the original file used bare `button`,
 * `input`, `table` selectors, which would otherwise clobber every page.
 * Custom properties are scoped the same way (not on :root) for the same
 * reason. Dark mode keys off [data-bs-theme="dark"], the SAME attribute
 * useTheme.ts already sets for the rest of the app (the original used
 * its own separate [data-theme] key) — so this page follows the one
 * global theme toggle instead of running a second, disconnected one.
