## Data flow ## Data flow
> **Correction (found in live testing):** the warp bends a path only at its *vertices*. A
> straight G0/G1 move is a 2-point segment, so warping just its endpoints draws a straight
> chord and hides the curvature entirely (measured ~320px of bow on bed-spanning lines
> collapsed to nothing). `projectSegments` therefore **subdivides each segment in work space
> (~20mm steps) before warping**, so the rendered polyline follows the curve. Arcs were
> already flattened to dense vertices and are unaffected.
