What a component holds moves with its occurrence, and picks in the world land in the
component's frame:
- Sketches and construction planes show where their component is placed (free move, joint
drive, Capture Position); sketch.inspect reports sketch points in the world.
- frames.rs maps a command's world picks into the frame of the body they lie on (through the
inverse of its placement: a moved component or a pasted instance), points that make new
geometry into the active component's frame, and directions with them; instance body names
("Body1 (Pin:2)") become the component's body. Fillet/chamfer edges, shell/offset/draft
faces, face extrude/revolve, sketch on face, holes, sheet metal and plastic picks, primitives,
appearance faces, analyses. Once per command (not again for commands run by commands); the
active-frame fallback stays for commands without a table. Nothing changes while every
placement is the identity.
- component.move_bodies keeps a body where it is in the world (Document.body_offsets: from the
new component's frame to the one it was made in; renames and deleted components follow).
- The UI reads the placed model (Session::world_state) for display, picking, sketch editing and
dialogs; live previews use it once anything is placed.
Tests (engine): sketches and construction planes move (and turn) with the component; world
picks fillet, sketch, hole and make boxes in a moved component; a pick on a pasted instance;
move_bodies keeps the world place there and back; a sketch on a face follows a Move feature.
QA's s34 now runs.

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.

- 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.
