 Browser acceptance ran in Chrome at 1600x1100 and 390x844. Passed: actual world-space movement of two nodes at two scales; editing without movement; resizing; gesture undo/redo; SVG connection start aligned to node geometry after resizing and panning; refresh document and viewport restoration; pointer-anchored Ctrl+wheel zoom; create/duplicate/delete/undo/redo; viewport equals window bounds and no horizontal mobile overflow. Production webpack compilation passed. Isolated-worktree dependency symlinks caused standalone tracing warnings (28 files outside tracing root), so deployment package completeness is not claimed. Local account-session request returns 404 because the shared account service runs in the full site; production authentication was not changed or validated here. Model generation remains explicitly unavailable.
 
 Evidence screenshots are retained as intentional review deliverables under docs/evidence/canvas-rebuild/, not temporary output. Local server, dependency links and generated build/cache output are removed after acceptance. PR targets main for manual user merge; no deployment performed.

+## Theme and unobstructed canvas follow-up
+Added persistent light/dark themes covering the grid, cards, input fields, floating chrome and connection lines. Removed the left tool strip and the inspector. The tool strip is now a centered bottom dock; zoom/history floats at top right. Clicking empty canvas opens add actions; node ellipsis or right-click opens copy/delete/connect actions near the pointer. Escape or clicking elsewhere dismisses the menu. Node editors remain inline. Browser checks cover dock placement, theme persistence and contextual CRUD in addition to the existing gesture suite. TypeScript, 13 canvas-branch tests and webpack compilation passed; 19 S3-branch tests passed separately. User explicitly authorized merging PR #23 and #24 in this follow-up. Shared account-service and standalone tracing limitations remain as noted above.
