/**
 * Pinning tests for the Zod-cap-vs-DB-column class (audit H2, M2, M4, M11,
 * L1, L8d, L8e + adjacent invoice item/bank caps): every form-facing string
 * cap must fit its DB column width, or an over-width value passes Zod and
 * dies at Prisma as a 500 (P2000) instead of a clean Czech 400.
 *
 * Each case asserts BOTH directions: width+1 chars must FAIL the schema, and
 * exactly width chars must PASS (guards against over-tightening — stored
 * values can never exceed the column width, so re-submitted edit forms stay
 * valid).
