//! Shared parsing helpers for CUDA runtime tuning environment variables.

/// Resolve a byte-valued tuning knob from an environment variable whose value is
/// expressed in MiB, falling back to `default_bytes` when unset or unparseable.
///
/// Used by the allocator (free-list cap) and the client (memory-pool release
/// threshold) so the MiB→bytes conversion lives in exactly one place.
