	18	+## Geometry
	19	+
	20	+Each section is centred on the origin in the XY plane, its longer side along Y, and extruded along +Z by `length`.
	21	+The section is the reference model's own outline at mid-length, written in the recipe as a table (`PROFILES`, in
	22	+`part.py`): loops of lines and arcs (each arc by its two ends and its midpoint), the outside first, then the cavities
	23	+and bores.
	24	+
	25	+## Parameters
	26	+
	27	+| Parameter | Meaning |
	28	+|---|---|
	29	+| `profile` | the section (table above) |
	30	+| `length` | mm |
	31	+| `finish` | anodising colour, `clear` or `black` (appearance only) |
	32	+
	33	+## Sources

	35	+There is no manufacturer drawing behind these sections: **the geometry was measured from the published reference
	36	+models** below. Each model's cross-section was cut at mid-length with OCCT and every edge read exactly (line ends;
	37	+each arc's ends and midpoint), centred on the section's bounding box and rounded to 0.0001 mm; the recipe re-draws
	38	+those outlines in its own code. Every preset is checked against its own reference model (the catalogue entry it comes
	39	+from): bounding box within 0.05 mm (0.5 % over 100 mm), volume within 2 %, section area within 2 % and the section
	40	+outline within 0.1 mm of the model's.

	53	+Simplifications: the 40 × 80 model's eight spline edges are drawn as 16 chords each (within 0.01 mm); otherwise none
	54	+beyond the models' own (no end threads). The B-type and I-type models are generic sections of those slot systems;
	55	+makers' sections differ in detail, so check a specific maker's drawing where it matters.
	56	+
	57	+The catalogue's `tslot_*_l0600` entries are step.parts' simplified stand-ins (a rectangle with one rectangular groove
	58	+per face), not T-slot sections, and are not presets. Preset list: from the step.parts catalogue (MIT), see
	59	+`library/NOTICE.md`; entries without a length (the base models) are presets at the model's own length.
