A panel drop-down taller than the window ran past its bottom edge, so the
last rows (Sketch → Create → Intersect and below) could not be reached. The
rows now scroll inside the window, and a row reached with the arrow keys
scrolls into view. Row ids no longer depend on the enclosing Ui, so the
keyboard focus still finds them inside the scroll area.
Projecting a cylinder's wall or the face of a round along a circular edge
failed with "face projection has an open or invalid boundary": these
surfaces are stored in halves joined by hidden seams, and the projection
dropped the seams but kept only the picked half. It now projects the whole
patch, the face as drawn, through the same surface_patch the viewport uses
to highlight it.
* Loop blends accept straight wall seams that are not lines
Filleting or chamfering the top outline of two overlapping cylinders whose
concave edges were rounded failed with "the wall seams must be straight":
the round's contact lines with the cylinders are straight NURBS curves, and
the loop blend only accepted seams stored as lines. A seam now counts as
straight when every sample lies on its chord; it is trimmed as a line as
before.
* Fillet and chamfer arrows point into the body
The radius arrow pointed out of the body along the edge's bisector, so
dragging it away from the edge grew the round. It now points into the
material, like the shell's thickness arrow: dragging toward the body grows
the radius or distance, dragging out of it shrinks it.
* Fillets along a straight edge between two cylinders: the rolling-ball blend trims curved cap edges to its contacts
The edge where two overlapping extruded arcs meet is a straight line between two cylinders
ending on planar caps. The rolling-ball blend built its sections and surface, but only
straight seams could be shortened to the contacts, so a circular cap edge was refused with
"a curved edge where the blend ends". Curved seams now keep the part of their curve between
the new ends, found from the nearest of a few samples (a search from the far end of a long
arc can settle on the opposite side of the circle).
The ball's surface projections start from each face's last answer instead of a cold search,
falling back to one when the warm answer leaves the surface's parameters or is farther than
the last point: about 4.5x faster per fillet (370 -> 80 ms), so dragging the radius is usable.

* Curve blend: refuse a closed curved seam where the blend ends
A seam that starts and ends at the same vertex (a full circle) has no
"between" two contacts, so trimming it built a broken edge. Return
"not supported yet" instead. The curved-seam trim moves into
trim_curved_seam so it can be tested directly.
