- Fix frontend Network error: API_BASE now defaults to empty string (same-origin) - Fix 3 files: api.ts, AuthContext.tsx, Dashboard.tsx - Add Canvas 2D context mock in tests/setup.ts for jsdom - Fix -0 vs +0 in ZoomPanController.getViewport() - Add IntegrationWorkflow.test.ts (35 tests, full CAD workflow)
