Sprint 14~22 — egui 리본 UI + OcctKernel B-rep + 가로보/신축이음 + 선형 좌표 + USD 익스포트 + WASM + CI/CD + 테스트 4층

Sprint 14: egui TopBottomPanel 리본 + CollapsingHeader SidePanel (상부구조·추가부재·선형·프로젝트)
Sprint 15: IncrementalDb 전 Feature 타입 확장 (girder→7종), dirty-tracking 20 unit tests
Sprint 16: Gitea + GitHub Actions CI/CD (check/test/clippy/fmt + 멀티플랫폼 릴리스)
Sprint 17: AlignmentTransform + AlignmentScene — 선형 국소 프레임 → 세계 좌표 변환
Sprint 18: OcctKernel 교각(16각형 기둥+코핑) + 교대(흉벽+푸팅+날개벽) B-rep
Sprint 19: CrossBeamIR + ExpansionJointIR — IR/DSL/kernel/scene 전 계층, sweep_profile_flat_x
Sprint 20: 테스트 4층 — Layer1 insta 스냅샷(7종), Layer2 기하 불변량(19), Layer3 두-커널(7), Layer4 proptest(7) — 61 tests pass
Sprint 21: cimery-usd PureRustKernel 실제 기하 변환 + BridgeExporter 증분 캐시
Sprint 22: viewer wasm feature + wasm-bindgen/web-sys + GitHub Actions Cloudflare Pages 배포
