//! Token limits of one upstream model.
//!
//! [`ModelLimits`] is the per-model ceiling a codec clamps a request to: the
//! context window, the output-token cap and the optional thinking budget. The
//! provider catalog carries one per model; the codecs read it when they render
//! an upstream request.
