/* ─────────────────────────────────────────────────────────────
   LevTech incident-detail drawer — Wave 1 Step 3.
   Ported from design_handoff_levtech_wave1/app.css lines 556-724.
   Adjusted for native <video> playback (the prototype used a styled
   gradient mock-clip). When video_url is null, the mock-clip styling
   serves as the placeholder.
