content onto the canvas and have Gemini 2.5 Flash analyze it, classify each piece
into the appropriate folk-* shape type, and propose a multi-shape layout with
semantic connections.
- POST /api/mi/triage endpoint with structured JSON output from Gemini
- TriageManager orchestrator (analyze, removeShape, commitAll via MiActionExecutor)
- MiTriagePanel floating preview UI with shape cards, connections, Create All/Cancel
- Canvas drag/drop overlay + paste handler integration
