continuous-integration/drone/push Build is passing
- Introduced `legacy-shaders.js` containing vertex and fragment shaders for rendering. - Implemented `model-io.js` for parsing and encoding GLB files, ensuring compatibility with glTF 2.0. - Created `project-panel.js` to manage project resources and survey overlays, enhancing user interaction. - Added `solar.js` for calculating solar positions based on UTC time, latitude, and longitude. - Developed `three-renderer.js` as a standard backend for Three.js, managing scene rendering and material synchronization. - Included a new GLB model `dum.glb` for testing and demonstration purposes. - Established `data_checks.mjs` for validating model data and ensuring integrity of assets. - Created `prepare_export.py` to facilitate Blender GLB exports, maintaining material and node references. - Added `vendor_three.py` to download and configure a local version of Three.js for the project.

loceniceId, stdWhen, stdBlind, windowNode and interiorLayer must stay on objects.

After exporting all variants to GLB, run tools/prepare_export.py.

A changed wall or cabinet also requires checking web collision volumes / camera presets.
