//! zit — a Fossil version-control system implemented in Zig.
//!
//! zit is a direct port of the Fossil formats and protocol as specified by
//! four companion Internet-Drafts, kept in `docs/rfcs/`:
//!
//!   * delta   — draft-fossil-delta-format-00     (byte-level delta encoding)
//!   * artifact— draft-fossil-artifact-format-00  (manifest/control-artifact cards)
//!   * reposta.— draft-fossil-repo-state-00        (derived branch/tag/leaf/trunk views)
//!   * sync    — draft-fossil-sync-protocol-00     (HTTP sync/clone protocol)
//!
//! Implementation order follows the RFC dependency layering:
//!   delta  ->  artifact  ->  repostate  ->  sync
//!
//! Each module cites the section of its RFC that governs a given rule.
