@@ -47,3 +47,11 @@ Run: `npm run build:preview` then serve `dist` (dev server shows a blank page).
- **Known weaknesses:** the 92%-wide panel hides the board while reading (visible at chapter entry, in gaps between case studies and at exit); phone screenshots read dim; ~140 px on phones; test-only telemetry.
- Screenshots: docs/overnight/round5/.
## Round 6: Dashcam (photo mode + postcard)
- **What:** a camera button in the drive controls (or key `c`) folds the reading plates away, closes letterbox bars, and shows a dashcam frame with live telemetry (REC dot on the bass, chapter + exit, Bucharest clock, route %, coordinates + name). The lens drifts with the pointer (+-1.6 units, re-centres after 3 s idle). "Save postcard" downloads a 1600x900 PNG of the live scene with credit line, a white shutter flash and a synthesized shutter click when sound is on. Tab title becomes "DASHCAM · 47% · INFRASTRUCTURE · 03:51" while open. Esc/c/Close exits and returns focus. Absent for reduced motion/static/visitor-pause and below 768 px.
- **Why:** the recurring weakness of rounds 1-5: the reading panels hide the world. This gives a juror one deliberate full-screen moment, and a shareable artefact.
- **Build:** journey/dashcam-feed.ts, scene/world/dashcam-lens.ts, composables/useDashcam.ts, lazy components/DashcamFrame.vue + lib/dashcam-postcard.ts + audio/switchboard-click.ts, styles/dashcam.css. 820 tests, initial JS 117.73 KB gz (2.3 KB left), lazy chunk 3.7 KB gz.
- **Verdict: KEEP with fixes** (Fable, hardware GL): Contact bars were striped (aubergine outro bars under black), now frame draws its own bars; canvas resized on open due to overflow lock (removed); focus dropped after save; `c` worked on phones where the button is hidden; round 5's HUD exit tab had been dropped, restored; REC dot got a no-music blink.
- **Known weaknesses:** postcard is the 1440x900 buffer scaled to 1600 (slightly soft) and keeps the lens bars; no phone version; shutter click only while soundtrack runs; two chapter-label vocabularies in the frame.
