[Jul 8] Hinge chunk, F combines faces, edge loop select cursor-aware. Hinge chunk: most specific subtractive-B dispatch. Two 1-quad-deep strips bent over a crease (bottom face + side face over the cube edge) — B deletes the box under the bend. Each hinge station's inner vert is the parallelogram completion; both strips rebuild with completions plus one cap per hinge end. F combines faces: face-mode F now turns each selected region into one n-gon spanning its rim. Delete the region, sweep everything interior including verts, make the face over the ring (slot-wound). Merged face takes the lowest-id material, stays selected. Ring verts left as pure subdivision residue (exactly two colinear edges) fuse away — one-side subdivide combines straight back to the original quad, neighbors' 5-gons heal with it. Edge loop select (double-click) now uses cursor position to pick the hug face on ties. Previously, when both faces of the seed edge scored equally (cubes, loop-cut cubes — any 90° geometry), the tiebreaker was lowest face id (arbitrary). Now the face whose screen centroid is nearest the click wins. Alignment-based scoring still wins when one face is genuinely straighter (cylinder rims).
