-- After it, `{/person} ({/person.first})` renders two people, as does `{/sv_SE.person as a}{/sv_SE.person as b}{a} & {b}`. `{w} {uppercase(w)}` renders `b G` where `w` is a choice of letters, and `{/city.name}, {/country[SE].name}` and `{/country[SE].name} / {/country[NO].name}` both load.
-- Deletes the token-order rules (`drawsApart`, `readFold`, `branches`, the pairwise replay), the expansion hold fence, `drawGroup`, the own-family fence and the cell-reference fences, and revises the decisions that point here. The remaining draw checks are names, paths through names, cycles and the repeat cap.
-- Fixes on the way: `{/sel}|{/sel}` panics out of `Fake` today where two draws land on rows whose cells select different rows of another table; it must render.
-- Rewrites the README's Computation, References, Draw group, Correlated fields, Linked tables, Names and "One draw, one spelling" sections; the Linked tables section says which pick's weights govern a family, since the bound row decides.
-- Keeps a name read once where no reference can stand, such as `{/score as s}{calc(s * 2)}` over a numeric category `score`, loading. Widens the refusal of a name read once to every binding, a path into it or a reference path bound included, since `{n.x}` read once is then `{/ref.x}`, and deletes the names fence over draw groups and nested repeats (`checkUses`, `readsHeld`).
-- Say how a record's columns and a struct's tags read one pick, so the `first` and `sex` columns of one `sv_SE.person` record, or one struct's tags reading them, still describe one person.
-- Re-pin seeded output and `testdata/shipped_shape.txt` in their own commits; the CHANGELOG names the grammar change.

 The decision "With only the shipped set, a category loads on the first call reaching it; beside a `--data-path`, every category loads in `New`" parses the whole shipped set on every `--data-path` run, about 45 ms today and seconds once items 61 and 78 land.
