1//! Every length limit on what an agent or operator writes, one submodule per
2//! thing written. The request types' `#[garde(length(…))]` attributes name
3//! these, and schemars reads the same attributes into each schema's
4//! `maxLength`, so the check, the schema and the database CHECK quote one
5//! number.
6//!
7//! `_BYTES` limits count UTF-8 bytes (`octet_length`), `_CHARS` limits count
8//! Unicode scalar values (`char_length`), as the column's CHECK does.
