Rebuild the Joke Shop as the Sunset Strip block

- Replace the alley with the 27 m Comedy Store-inspired hall, signature canopy, circular blade sign, red curtain bays, west entrance, low-rise neighbours, dry hillside and opposite frontage.
- Add day/night/across-street concept frames and real-site mapping notes.
- Expose the Joke Shop day stage in the realism captures and refresh the gallery shots.
- Render multiline HUD/wand strings correctly and list carried items in the wand panel.
- Add the Joke Shop layout/budget tests and update docs, roadmap and changelog.

+# The Joke Shop references
+
+AI-generated art-direction frames for the fictional Joke Shop, based on the
+real Comedy Store block at 8433 Sunset Boulevard. They are generated with
+`tools/scene_concepts.py generate --group scene --only ...` and are not shipped
+game textures. The geometry mapping and source links are in
+[`../../../joke-shop-map.md`](../../../joke-shop-map.md).

+alley design. They no longer describe the current Joke Shop map.
