Shaper Origin SVG semantics:
- White fill (#FFFFFF) = inside cut (vector follow along the path — faster, used for boundary/cutout)
- Gray fill (#808080) = pocket cut (area removal — raster/spiral clearing, used for interior cavities)
- Black fill (#000000) = outside cut
- `shaper:cutDepth` attribute sets depth per path
- BenchPilot mode may cut layers in ANY order (not necessarily top-down), so each layer must only contain material not already removed by other layers
- Tabs are bridges in the boundary trough that hold the piece in stock — they should NEVER affect interior/model geometry

**Why:** These semantics drive the entire SVG generation logic. Getting fill colors wrong means the machine uses the wrong cut strategy.

**How to apply:** Always verify boundary paths get white fill and interior paths get gray fill. Tabs only subtract from boundary.
