/* dash-signerqueue.css
 * ─────────────────────────────────────────────────────────────────
 * Aesthetic flavor: "operations-cockpit"
 *
 * High-contrast amber-on-black aviation/radio-control-panel feel.
 * Inspired by old avionics caps-lock strips, tower-clock indicator
 * lamps, and the dense IBM Plex Mono columns of a flight-deck
 * checklist. Hover states glow amber; pending rows pulse soft
 * yellow; signed rows are green-on-black with a faded tail.
 *
 * Deliberately distinct from the existing nine surface flavors:
 *   - cyberpunk Scandinavian (index)
 *   - utilitarian dashboard (panel)
 *   - Swedish-newspaper Q&A (aedln0d chat)
 *   - engineering schematic (aedln0d kg, dash-retrieval)
 *   - terminal sparklines (healthlog)
 *   - warm-paper editorial (docs)
 *   - green-CRT (dash-agents)
 *   - bioluminescent forest (dash-aedlnet)
 *   - procurement-ledger (dash-bidpipeline)
 *
 * Palette tokens are self-contained — no global reset.
