Only swing doors (hinged/double/french) baked an open clip into the GLB — they carry a `pascalSwingLeaf` marker the exporter reads. Every operation door type (sliding, pocket, barn, folding, garage-sectional/rollup/tiltup) baked its `operationState` straight into mesh vertex positions at build time, so the exporter had no re-poseable node to sample and the artifact never flagged them `openable`. Give operation doors the same build-once + pose-at-t split windows already use. Each builder now emits its moving parts in a named group at the CLOSED pose, and `poseDoorMovingParts` (the single source of truth, shared by the live system and the GLB exporter) drives the open motion: - sliding/pocket/barn: rigid leaf translation - garage-tiltup: rigid hinge about the lintel - folding: hinged accordion chain (nested groups, per-joint fold) - garage-sectional: per-panel groups posed along the overhead curve - garage-rollup: the one type whose live geometry changes (slats roll onto a drum, which a glTF clip can't express) keeps its full-detail live rebuild; the curtain is wrapped in a top-pivoted group the exporter scales up into the lintel as the baked approximation. The exporter samples each operation door's motion into keyframe tracks (16 segments) so the non-linear rigs (curve, accordion) stay faithful, and stamps `extras.openable` + `extras.clips` so any glTF consumer can play it. Tests: per-type kinematics (groups build, rest closed, open) + sliding/roll-up clip baking (sampled position/scale tracks). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Asset CDN Helpers
import { resolveCdnUrl, ASSETS_CDN_URL } from '@pascal-app/viewer'
// Resolves relative paths to CDN URLs
const url = resolveCdnUrl('/items/chair/model.glb')
// → 'https://pascal-cdn.wawasensei.dev/items/chair/model.glb'
// Handles external URLs and asset:// protocol
const externalUrl = resolveCdnUrl('https://example.com/model.glb')
// → 'https://example.com/model.glb' (unchanged)
