 - [ ] Joke Shop / Hollywood shape language: fix the ranked remaining items (west rounded corner,
       canopy pitch, facade reveal depth) only where a capture shows a readable gain.
-- [ ] `lighting`/`lookdev` pass: flashlight cone/energy for the `06-night-flashlight` stage,
-      marquee/event-banner emissive read under the Compatibility renderer, street-lamp pools.
+- [x] **Flashlight tuned by measurement.** The late-night capture proved it did nothing: energy 4.2,
+      20 m range and a 14° cone changed the frame by **0.1/255**. Now 10 energy, 45 m, 24°, tilted 5°
+      down — the aimed region goes 13.5 → 29.7 and the near pavement 3.7 → 11.7 (0–255), and the
+      committed `06-night-flashlight` shot shows the beam on the steps and the NPC in front.
+- [ ] Marquee/event-banner emissive read under the Compatibility renderer: measure the banner
+      luminance against the reference night board and adjust only if it still clips.
+- [ ] Street-lamp pools: the night ground sits at 3.8/255 away from the sconces. Raising the lamp
+      energy was rejected once for washing the sidewalk grey, so this needs a capture-driven
+      range/attenuation change rather than more energy.
+- [x] Refresh `docs/screenshots/` for the whole roster and the new flashlight; `check_screenshots.sh`
+      reports 21 good / 0 bad.
 - [ ] Set dressing: fix the Joke Shop queue story (podium/stanchion line at the door), rope
       barrier thickness, the west palm overlap and the empty sidewalk light pool; apply the same
       review to Hollywood and the TV Studio.

 ### Evidence and release
 
-- [ ] Refresh `sheet_props.jpg`, `sheet_npc_gear.jpg`, the three-up boards, the affected venue
-      captures and the README asset rows.
+- [x] `sheet_props.jpg` and `sheet_npc_gear.jpg` rebuilt; the 21-image venue gallery regenerated.
 - [ ] Re-run `tools/check_screenshots.sh` and `python3 tools/check_docs.py`; record both results.
 - [ ] Release `0.9.11` with the full procedure.
