/* TARS control-surface theme for media.streamless.io.
 *
 * Deliberately the same visual language as the Kitchen director view
 * (SceneCard.tsx), which in turn came from TARS-Atem's tars-control.html:
 * near-black surface, hairline borders, a 3px tally strip that glows only when
 * it means something, oversized condensed numerals, and uppercase micro-labels.
 * An operator moving between the director board and this page should not have
 * to relearn what red and green mean.
 *
 * This is a SEPARATE FILE from tokyo-night.css, which is left untouched on
 * purpose: rolling the look back is reverting three <link> tags, not restoring
 * a stylesheet from a backup.
 *
 * Class surface matches what login.html, dashboard.html and admin.html already
 * emit -- no markup was restyled by renaming things.
