Variable: QR\_CODE\_MAX\_BYTES

const QR_CODE_MAX_BYTES: 2953 = 2953;

Defined in: shared/qr-code/schemas.ts:11

Largest payload a QR symbol can carry: version 40, error-correction level L, byte mode. Anything above this cannot be encoded at any ECC level, so it's rejected up front with a useful message rather than a RangeError from deep inside the encoder.
