Made of little things.

# Room artwork and MP3 cleanup

Replace all 32 demo camera backgrounds using the current geometry/camera schemas,
including 14 priority door approaches, six frame recovery views and frog angles.
Use the existing PS1 art direction: textured low-poly prerenders, restrained
olive/umber/teal, weathered surfaces, pinned case notes/photos/maps, cleaning gear
and flat litter. Preserve the olive/brass evidence-terminal HUD and app-owned
theme policy. Keep arrivals and paths clear, with readable doors and actor scale.

Use the built-in image generation tool, one schema-guided image per view. Inspect
composition against the schema and correct invented obstacles/ambiguous doors.
Deliver only 640×480 JPEGs to the repository; remove both superseded room-art sets.
Check in all current schemas, exact prompts, asset hashes and JSON camera bindings.
High-resolution generation files are not part of the publishable source archive.

The user explicitly requested MP3s and does not need audio editing masters.
Retain the existing 33 normalized MP3s byte-for-byte; remove original downloads,
duplicate WAV reviews and superseded takes. Retain prompt/settings/result/hash
provenance, update validation to check the surviving files, remove obsolete
WAV-preparation scripts and make future catalogue delivery MP3. Do not promote
planned sounds to generated or claim a new listening review.

No new NAP, host authority, network service, backend, dependency or build change.
Verify linked images/JSON, MP3 hashes/provenance, gameplay and sharing roundtrips,
actual image/audio decoding in the host, frame/touch/theme/missing-domain behavior,
conformance and the source/HTML budgets. Capture new representative previews,
inspect the selected Listing image, stop the owned preview and save a local
checkpoint. Do not publish or push.
