//! Zero-copy collections for on-chain account data.
//!
//! All collections operate directly on byte slices -- no heap allocation,
//! no `Vec`, no `Box`. They are BPF-safe, deterministic, and audit-friendly.
//!
//! ## Available Collections
//!
//! - [`FixedVec`] -- Bounded dynamic array with push/pop/swap_remove
//! - [`RingBuffer`] -- Fixed-capacity circular buffer for journals/logs
//! - [`SlotMap`] -- Fixed-slot map with generation counters for safe handles
//! - [`BitSet`] -- Compact bit array for flags and bitmask operations
