Recipe 2 — Extract Edges

What: Get edge curves from a surface/brep, organized by type.

Zone Map: [Surface/Brep] → [Deconstruct Brep]

Pipeline

[Surface / Brep]
       │
       ▼
[Deconstruct Brep]
       │
       ├── F → faces (surfaces)
       ├── E → all edge curves (flat list)
       └── V → vertices

Alt — Brep Edges (cleaner for edge-only):

       │
       ├── E → exterior (outer boundary) edges
       └── I → interior (hole/trim loop) edges

Output

Edge curves (flat list or split by type).
