Cross-platform primitives (sync, time, thread) for native and wasm32.
Documentation
//! Flash engine internals. [`FlashInner`] (`inner.rs`) is the SINGLE owner of
//! all engine state: the virtual clock ([`inner::Clock`]), the one
//! lock-protected scheduler core ([`inner::Core`], split into
//! [`inner::Registry`] + [`inner::Scheduler`] data) and the real-I/O pacer
//! (`pace::Pacer`, with its lazily-spawned eternal thread holding a strong
//! `Arc` to its OWN instance). The process engine is the lazily created
//! [`FLASH`] instance.
//!
//! Engine methods are instance-addressed (`&self` on `FlashInner`); nothing
//! below `FlashInner` reaches for the [`FLASH`] global, so local instances
//! behave identically. Everything outside `system/` consumes thin free-fn
//! forwards (each one `FLASH.method(...)`) re-exported below.
//!
//! The pure-scheduler tests in `flash/tests.rs` run on LOCAL instances
//! (`FlashInner::new_arc`, cfg(test)) — only the primitive-path tests (and
//! production) drive the global [`FLASH`] through the forwards.

/// Participant credit accounting (dedicated pacers, bridged waits, blocking
/// pacer bracket) split out of the scheduler — see `credit.rs`.
