The IR supersedes both intermediate designs (requirements D6, D7):
station/tools/docgen and the graph model that briefly lived in graphgen.
Shipping them beside atlas2/docgen would mean two graph models, which is the
thing the architecture argues against.
Carried across rather than lost:
- style/extract.py and tokens.py, the offline theme harvester (R31). Rewritten
to emit a *theme* — a slot-to-hex binding — rather than a whole style file,
since what harvesting recovers is which colour a slot should be, not what a
kind should look like.
- graphgen/README.md, rewritten for what graphgen actually is now: the
schema explorer. It fixes the blank station-index entry at run.py:304.
Two bugs found while doing it:
- Canvas and ink are the two lightness extremes, not the two most common
values. In a Graphviz SVG every label carries a fill, so the ink outnumbers
the canvas 87 to 43 and the old rule produced a theme whose text was
invisible against its own background.
- A name defined in both branches of an if/else produced a duplicate id, which
failed validation on docgen's own source. Disambiguated by line.
