//! Runtime budgets and public byte-count value types.
//!
//! Parser limits, runtime input limits, execution limits, and trace snapshot limits are separate
//! domains. Parser limits bound source ingestion and parsed program size;
//! runtime input limits bind raw input validation; execution limits decide
//! whether execution may allocate or continue; rule-attempt limits decide how
//! many executable rule lines a rule-attempt session may consume; trace
//! snapshot limits decide whether a borrowed trace event may be materialized as
//! owned bytes. Count types report measured lengths without erasing those
//! domains into plain `usize` values.
//!
//! Limits are policy values supplied by the host. Count values are observations
//! produced by parser, input, execution, or trace code. Keeping those roles in
//! distinct types prevents a source length, runtime input length, runtime state
//! length, return-output length, or trace-snapshot length from crossing into
//! the wrong budget by accident.
