# Hero furniture models — sources & licenses

Phase 2 hybrid furniture (DTD verdict C): the showroom builds **every** piece as a
crafted THREE primitive first (ships fully offline), then lazy-loads these real GLB
hero models over the matching primitive for the active room only. If a model fails to
load or is missing, the primitive stays — nothing here is ever shipped broken or
unlicensed.

All models below are from the **KhronosGroup / glTF-Sample-Assets** repository
(https://github.com/KhronosGroup/glTF-Sample-Assets), downloaded 2026-06-30.

## Pieces that stayed CRAFTED PRIMITIVES (no verified-license GLB sourced)

The following room-type hero slots kept their upgraded crafted primitive because the
CC0/CC-BY sample-asset set contains no matching furniture piece, and no other source
could be verified as correctly-licensed within scope (the task forbids shipping
unlicensed or unverified models):

- **bed** (bedroom) — primitive: walnut platform + mattress + duvet + pillows + throw
- **desk** (office) — primitive: walnut top + panel legs + emissive monitor + swatch boxes
- **coffee-table** (living + lobby) — primitive: stone/walnut drum-base round table
- **pedestal** (gallery) — primitive: stone plinth + turned sculptural object

Bookshelf, olive planter, benches, reception desk, nightstands, dresser, armchair,
rug, framed art, wall label, and all ceiling fixtures are crafted primitives by design
(cheap, license-free, and matched to the spec).

To add more hero GLBs later: drop a CC0/CC-BY `<slot>.glb` into this folder matching a
key in `MODEL_URLS` (showroom.js) — `bed`, `desk`, `coffee-table`, `pedestal` — record
its source + license here, and it will be lazy-loaded over the primitive automatically.
