lab: top-right link -> API docs

lab: preview GLBs for all 5 datasets (#2)

lab: preview GLBs + gated downloads for articulated-storage-and-appliances (#1)

Brand: 'projectsim' lower-case throughout

Add a Containers tab (bottles-and-containers: cans, jars, mugs)

Deep links from dataset cards: ?class= / &item=, thumbs, class-aware note

Deep-link the Dataset button to the active class folder

add 3 static-asset tabs (pallet_boxes, gas_cylinder, pallet_racking) + generalize class-scenes -> class-static so their HF-link panel replaces the articulation UI

rename to just 'Lab'; scenes tab hides articulation controls and shows HF links instead

viewer: re-attach DRACOLoader (was reverted by prior patch that used a stale local cache)

viewer: log GLB load errors + surface a friendly message instead of silently empty stage

viewer: add loading spinner while a scene / item GLB is downloading

viewer: attach DRACOLoader so draco-compressed scene GLBs (bedroom/kitchen/garage) render

Take it home: align download commands with what the new datasets actually ship. Isaac/usdview grab <vid>.usda + textures/; MuJoCo grabs mjcf/** (xml + visuals/ + collision/); Blender grabs .glb (no .blend files). Uses huggingface_hub snapshot_download in place of per-file curl.

fix: shipped GLBs are Y-up (not Z-up like the old viewer glbs). Drop the model -π/2 fix-up rotation and transform pivot/axis Z-up -> Y-up in each catalog.

Point at the new consolidated datasets (warehouse-manipulation-and-states + articulated-storage-and-appliances); ship per-class viewer catalogs in the space; add ovens.

Take-it-home: engine selector (Isaac/MuJoCo/usdview/Blender) + OS-aware commands, auto-detect, and agent prompt

Rename Space display name Procedural Lab → Articulated Lab

buttons: site pattern (deep-copper default, accent hover), wider item list, label tweak

copy: execCommand fallback for embedded/iframe contexts

ProjectSim design system (site palette/fonts) + copy confirmation

header: button-styled links

rail: curl download flow, new-tab links

header: open links in new tab; drop API docs

fix: stale-load race leaving previous model in scene

v0.1.0
