 *
 * Named `_resetForTests` until this audit, which said it RESETS something. It does not: `compose`
 * is pure, `USER_AGENT` is computed once at module load and this call cannot change it. A reader
 * looking for the state it reset would find none, and a test author might reasonably expect a
 * call here to alter `USER_AGENT` for the rest of the file.
 *
 * Not async either — nothing here awaits.
