- Miter gains a from_center option: pivot at the end CENTRE so it notches a
corner instead of cutting full width. Add a +angle and a −angle from centre on
the same end to bring it to a point (picket fence). Feature.from_center;
geometry.miter_cutter honours it; Joinery panel checkbox (miter only); CLI
feature --miter-pivot edge|center; wood-feature tool arg; serialization.
- Chamfer preview now shows the actual bevel slivers it removes (board −
chamfered board), like the miter wedge — instead of a flat face slab.
_chamfer_removed_mesh, with the face-highlight as fallback.
- tests: center miter notches a corner, two center miters make a point,
from_center roundtrip, chamfer preview is real geometry. 247 pass.
Re-run gen_wood_tools.py for the voice tool to expose --miter-pivot.

Two issues Rob hit:
1. Miter pivoted at the END CENTRE, so 45° only notched a corner — you couldn't
cut edge-to-edge. miter_cutter() now pivots about an EDGE of the end, so a
45° miter is a true full-width corner cut; the angle's sign picks which edge
stays long. Factored into geometry.miter_cutter so the wedge preview uses the
exact same cut. edit_feature keeps a miter on an end face.
2. The Joinery panel showed every input for every feature, so most knobs did
nothing for a miter (only miter/bevel) or chamfer (only width), and the face
dropdown offered faces a miter can't use. The panel now shows only the
relevant rows per kind (KIND_FIELDS) and limits faces per kind (KIND_FACES:
tenon/miter = ends only).
tests: 45° miter wedge spans the full width; miter face stays an end; panel
shows angle-only for miter, width-only for chamfer, box fields for mortise.
243 pass.

The cyan (select) / red (edit) overlay for a miter fell through to the
tenon/mortise box branch, so it looked like a 1" pocket at the end instead of an
angled cut.
- viewer._miter_wedge_mesh: build board ∩ cutter (the piece the miter removes),
placed in world space, and return that as the preview/highlight mesh; falls
back to highlighting the end face when the angle is 0.
- factored tessellation into _solid_to_polydata; miter excluded from the
normal-axis spin step.
- test: the miter preview is a wedge reaching the board end, not a centre box.
238 pass.

A new 'miter' feature angles a board's end — miter across the width (frame
corners, braces), bevel through the thickness (tilted blade), or both
(compound). Slots into the existing Feature system.
- scene: Feature.miter_deg/bevel_deg; END_KINDS={"miter"}; add_feature forces an
end face and defaults to 45° miter; serialization additive.
- geometry._apply_miter: subtracts a large block rotated about the end (Z=miter,
Y=bevel) so the viewer/export show the real angled end; guarded.
- cut list notes "miter 45° / bevel 15°"; instructions describe the angled end;
jigs suggest a miter sled/gauge for ≥3 repeated angle settings.
- cli feature --miter/--bevel; controller wood-feature passthrough; gen_wood_tools
wood-feature gains --miter/--bevel (re-run it for the voice tools).
- GUI Joinery tab: "+ Miter" button + Miter/Bevel angle fields (live edit/apply).
- tests: default 45°, end-face forcing, JSON roundtrip, cut-list note,
instructions, jig suggestion, and real geometry (volume reduced). 237 pass.
