"""OnCallEnv Red Shift — Ops Room Gradio theme.

Visual language: Datadog / Grafana / Linear. Cool grays, single electric-blue
accent for primary actions, amber for warnings, red for critical. No neon, no
scanlines, no cyberpunk flourishes. Optimized for projector readability during
a 3-minute pitch.
