- Add doc comments to the functions and tests this PR touches (Docstring Coverage).
- Share the toolbar width (toolbar_width/toolbar_columns), the rail widths and
CANVAS_MIN_WIDTH instead of repeating the values; no values change.
- Document dockWidth as the requested model width, which a narrow window may draw
narrower in either layout, and test model 520 / drawn <= 364 / canvas >= 200.
- Document that a dockWidth change is shared equally among columns within their
minimums and iconic caps; tie ICONIC_WIDTH/ICONIC_MAX_WIDTH to craft-ui's
DockStyle defaults (36/240) in a test.
- Replace the DOCK_ONLY thread-local and its guard with show_layout(dock_only).
- Move the test-only probe writes behind panel_docking::record, with no-op stubs
outside tests.
- Read an unknown or malformed saved toolbar_side as Start instead of dropping
the whole panel state; ui.set still refuses it.
