/**
 * Row types shared by the Postgres and SQLite adapters.
 *
 * These mirror the persisted columns 1:1 in snake_case. The repository
 * methods return these rows directly so route handlers don't have to
 * know which driver is underneath. ISO-8601 strings are used for every
 * timestamp on both drivers — Postgres stores them as TIMESTAMPTZ, the
 * adapter casts to/from text at the boundary, and SQLite keeps the
 * existing text format. This means timestamp comparisons happen in JS,
 * not SQL — a small performance cost in exchange for one less dialect
 * difference to maintain.
