//! Built-in curated MIME registrations (enabled by default via the `builtin`
//! feature). Disable with `default-features = false` if you want to provide
//! your own set.

//! This module also exposes named constants for common types, e.g.
//! `mrmime::builtin::TEXT_HTML`, `mrmime::builtin::APPLICATION_JSON`, etc.

// Define the builtin list exactly once; each entry -> MIME literal, extensions,
// constant name
