 *
 *   - Vertex handles on every polygon corner (orange dots).
 *   - Midpoint `+` handles between vertices to insert a new vertex.
 *   - Edge handles along each edge so the user can drag the whole
 *     edge perpendicular.
 *   - Same three handle sets for every hole in `node.holes`, with the
 *     `holeIndex` carried in each handle's payload.
 *
 * Uses `getRenderableSlabPolygon` for the visible fill (per-edge render
 * offsets against level walls + sibling slabs), but vertex / edge /
 * midpoint handles live on the **raw** `node.polygon` — matches the
 * legacy slab boundary editor which always operates on raw data.
