"""One-shot feasibility probe: render one product's catalog shard as Go literals.

Answers whether the shortcut storage model (compiled-in struct literals, zero
runtime parse) is viable for the 845-tool Schema catalog, by measuring compile
time, binary size and access cost on a single product first.

Deliberately drops field_provenance: it is 50% of the bytes and no runtime
consumer reads it, so a codegen design would keep it in JSON for audit only.
Keeping it here would make the size numbers pessimistic and the design wrong.
