"""Post-install check for the bundled catalogue and symbol library.

Run during the image build so an image can never ship with an incomplete
library or a truncated catalogue. `cross_check` alone is not enough: it proves
only that the catalogue is a subset of the library, so a short catalogue passes
it and then rejects perfectly valid projects at runtime with "not stocked by
Visaton". `check_shape` is what gives this gate teeth.
