//! Pure trading primitives — cross-cutting value objects for quantitative finance.
//!
//! Leaf crate: no internal dependencies. Only external: chrono, rust_decimal, serde, thiserror.
//!
//! # Provided types
//!
//! - [`Candle`] — OHLCV bar with timestamp
//! - [`Interval`] — time granularity (minute, hour, day, week)
//! - [`Symbol`] — trading pair (e.g., BTC/USDT)
//! - [`Ticker`] — universal asset identifier with venue/asset class metadata
//! - [`Currency`] — currency code (e.g., USD, BTC)
//! - [`PositionConfig`] — position sizing rules
//! - [`precision_boundary`] — canonical `Decimal ↔ f64` crossings with rich error enum
