Summary

Adds the Modern House Tour to the Interior category, using the same template as the living-room showcase (#91): an independent showcases/modern-house workspace, pinned release-hosted binaries (assets.lock.json + fetch_assets.py), a Pages build under /modern-house/, and a gallery card.

• Native Three.js cutaway house (306 meshes, 80,140 triangles, five half-float ambient EXR lightmaps, runtime sun) authored from one synthetic reference image with img2interior; seven room presets, sofa finish, wireframe.
• Viggle capture, default scene reconstructed from a Cycles panorama rendered inside the authored house; the original Viggle capture is kept as a comparison (Capture scene toggle).
• Portable .glb, packed .blend and the source ZIP are release downloads, never part of the Pages output.

Template parity with living-room

• showcases/modern-house/: assets.lock.json, scripts/fetch_assets.py, scripts/package_source.py, tests/test_fetch_assets.py, showcase-mode vite.config.js (stages runtime assets only).
• Root: workspace + build/dev/preview/sync:modern-house, prebuild chain, /public/modern-house/ ignore, dev directory-index middleware, gallery card, scripts/sync-modern-house.mjs, README section.

Merge blocker: publish the asset release first

npm run build runs fetch_assets.py, which downloads the pinned bundle from the release tag img2interior-modern-house-assets-v1. That release does not exist yet. Files are staged locally in showcases/modern-house/.release/ (gitignored); their hashes match assets.lock.json. Publish before merging:

gh release create img2interior-modern-house-assets-v1 --repo img2threejs/img2threejs-showcase \
  --title "Modern House assets v1" --notes "Pinned binaries for the modern-house showcase (see showcases/modern-house/assets.lock.json)." \
  showcases/modern-house/.release/modern-house-assets.zip \
  showcases/modern-house/.release/modern-house-source.zip \
  showcases/modern-house/.release/modern-house-portable.glb \
  showcases/modern-house/.release/modern-house.blend

Verified locally

• npx tsc --noEmit, npm run test:source (8 pass), python3 -m unittest discover -s tests in the workspace (10 pass), fetch_assets.py no-op on verified assets.
• npm run build:modern-house: 21 files, 81.5 MB, no portable GLB or .blend in Pages output.
• Headless Chromium (SwiftShader) on the showcase build: interiorStudy.status === 'ready', 306 meshes, download links point at the release URLs. Viggle capture reaches ready on the dev/prod build.
• Khronos validator: 0 errors / 0 warnings on runtime and portable GLB.

Limits (also in the README)

Layout, scale and hidden faces are authored estimates from one image; the native house and Viggle capture are independent representations, not registered; Viggle scale is arbitrary and unseen rooms are engine-filled; the portable GLB is a static baked snapshot (speckled walnut grain, dark mirror); no live GI or mirror; device evidence is headless-only.
