//! Story timeline (Phase 1 of the 1.2.6+ timeline feature).
//!
//! Timelines in inkhaven are built around three primitives:
//!
//! * `TimelinePoint` — a single `i64` representing ticks
//! since the calendar's epoch. Negative for pre-epoch
//! prequels. All time arithmetic is integer arithmetic on
//! this value; calendar complexity lives in `Calendar`.
//!
//! * `Precision` — how "exact" the user's intent is for a
//! given point. `Tick` is the base; `Day`, `Month`,
//! `Season`, `Year` are coarser. The AI critique uses
//! precision to decide what "overlap" means when comparing
//! two events with fuzzy dates.
//!
//! * `Calendar` — converts ticks ↔ human-readable strings
//! per the user's HJSON configuration. Three preset
//! expansions live in `presets`; `parse` accepts custom
//! per-project layouts via `config::TimelineConfig`.
//!
//! Phase 1 ships the storage, the calendar, the CLI surface,
//! and a flat Ctrl+V E picker. Swim-lane visualisation +
//! scope navigation land in Phase 2; AI critique in Phase 3.
