Joint dialog: picked origins mate as in Fusion, B's z opposite A's (two top faces put B upside
down on A, not inside it; a pin goes into its hole); the dialog's Flip turns B the other way
(sent as the command's flip, which turns B over from coinciding frames). Edit Joint shows the
same. Found by solvecraft-sketchux's scenarios.
Drive Joints: the first value box takes the keyboard with its text selected when the dialog
opens, so typing 90 and Enter drives the joint (found by solvecraft-sketchux).
Appearance: "In This Design" from appearance.list (in_design) when the engine has it; faces are
sent as face targets once the engine knows them.
Tests: face snaps mate face to face and Flip undoes it; typing into Drive Joints drives.

Library swatches by category (the engine's library when it offers one, else built-in looks:
metals, plastics, paints, woods, glass with opacity), the looks in this design, a colour picker
and opacity, and the objects to apply to (bodies/components or faces). A swatch dragged onto a
body or face in the viewport, or onto a body's row in the Browser, applies at once; Apply and
OK give the picked objects the current look; pre-selected bodies become the objects.
Browser: rows under a drag of another kind count as hovered, and the Browser's own drops no
longer swallow other payloads (egui's take_payload takes any type), so swatches dropped on its
rows land.

truck's connected components came out in hash order of face addresses, so a
boolean's faces, and everything built on them (fillet bands, STEP entity
order), changed from run to run. That made the oracle 35 export differ run to
run. Its old step_export flakes came from the orientation check's drifting
search, removed in 2db9e66. The result's shells and faces now keep the
order of the shell they come from (vendored truck-shapeops). Oracle results
are unchanged (73 PASS before and after). Test: the tee of oracle 35 with its
junction fillet exports byte-identical three times in one process (it failed
before).

Clicking OK during the Joint dialog's motion animation was lost about half the time: the
preview's busy spinner came and went in the dialog footer between frames, shifting the
automatic ids of OK and Cancel, so a click pressed in one frame and released in the next landed
on two different ids. The spinner's place is now always taken. Reproduced through the control
channel (6 of 14 OK clicks at different animation phases lost before, 0 of 14 after) and
covered by a test that presses OK with the preview busy and releases it once idle.
The Joints folder is drawn by component_rows for the root, after its folders (as agreed with
solvecraft-shell).

Start page (shown on launch without a file, and from the house button in the application bar):
New Design, Open, recent designs (kept in the preferences, newest first) and built-in samples,
each card with a picture rendered from the design in the background. Samples are scripts of
engine commands: the sample plate plus a sheet metal bracket, a hinge assembly with a revolute
joint, a plastic enclosure (lip, bosses, rest, snap fit), a bolted flange with a parametric
circular pattern and a vent plate with a parametric rectangular pattern (test: all build
without a failing feature).
Several open designs as tabs in the application bar: each keeps its own session (undo,
selection), camera and hidden/shown items; + and Ctrl+N open a new design, opening a file or a
sample uses a new tab unless the current design is blank, closing a tab with unsaved changes
asks Save / Don't Save / Cancel. Control channel: ui.documents and ui.home (docs/control-protocol.md).

With solvecraft-repo's curved-edge fillets (d72ec38), oracle 40's torus
groove comes out of truck in three pieces. Merging them made a band round the
torus whose single loop crosses itself, and the reader could not lay it out
("unsupported seam loop layout (2 runs)"). Each body's merged B-rep is now
read back. If that gives warnings and the unmerged pieces read cleanly, the
pieces are written instead.

- Bodies export (STEP, 3MF) in the colour they are shown in: an appearance,
else the physical material's look, else the colour the body was imported
with (Document::body_color / painted). Physical materials used to export
no colour at all.
- AppearanceCommand (Modify): a colour per body ("#rrggbb" or [r, g, b];
null follows the material again), kept in the design and across renames.
- Material looks move to solvecraft-doc (material_color); the viewport draws
appearance, material or imported colour, as exported.
- Engine test: brass and red ABS bodies export, re-import with their RGB, and
keep it through open and export again.

Free-form strips (a curved-edge fillet's B-spline bands round a saddle) vary
their normal too much along the loop for the loop-direction test, and the
hinted nearest-parameter search drifted on them: false 'runs clockwise'
reports on faces that round-trip exactly. The check now covers cylinders,
cones, spheres and tori (closed surfaces, where a loop read the wrong way
silently gives the rest of the surface); volume checks cover the rest. It
still flags all 8 sphere corners of a fillet box with their sense flipped.

ASSEMBLE panel (SOLID, SHEET METAL, PLASTIC): New Component, Joint, As-built Joint, Joint Origin,
Rigid Group, Drive Joints, Motion Link, Interference. Joint origins are picked by hovering:
faces snap to their centre (round faces to the centre of the nearer end), edges to their middle
(round edges to their centre), vertices to themselves, shown as glyphs with their z axis. The
Joint dialog has the motion type, angle, offsets X/Y/Z, flip, per-value limits and Animate (the
preview plays the motion); joints and drives preview on the placed model (world states).
Drive Joints moves live with a slider. Interference lists the overlaps and shows them red.
Joints appear in the timeline and in a Browser Joints folder (edit, drive, suppress, delete).
SHEET METAL tab in Fusion's layout: Flange (base, edge or contour, from the picks; height arrow
on the canvas), Hem, Unfold, Refold, Convert to Sheet Metal, Sheet Metal Rules (rule manager),
Create Flat Pattern (flat view with up/down bend lines, bend table, DXF export).
PLASTIC tab with SETUP: Boss, Lip/Groove, Snap Fit, Rest, Manage and Assign Plastic Rules; Rib,
Web and the shared solid commands on the tab.
Every feature dialog has live preview, Edit Feature and pre-selection; icons drawn in code.
Toolbar layout per tab in workspace.rs; tests for the dialog to command mapping.
