• Initial application: describe → preview/adjust → material → checklist →
  zero → carve wizard flow with a simulated-machine demo mode (chip --demo).
• Domain models (pydantic v2), SQLite persistence with autosave, trash, and
  carve history.

  bundled clip-art library, picture tracing (optional [trace] extra),
  rule-based layout, plain-language validation, Easel-compatible SVG export.
• AI designer/editor agents (pydantic-ai + Anthropic) with offline graceful
  degradation and undoable agent edits.

  character-counting streamer, jog/home/zero/Z-probe flows, safety
  interlocks, translated errors with guided recovery, FakeGrbl simulator.
• CAM for engrave/pocket/cutout with tabs, per-material feeds/speeds tables,
  multi-bit jobs with guided bit-change choreography, G-code generation.
