//! # Values (syntax side)
//!
//! The raw value of a content line, the cursor that edits it in place, and the
//! per-value-type [`Codec`](crate::tree::codec::Codec) impls, one module each,
//! mirroring the model's `value/`.
//!
//! [`IcalValueNode`](node::IcalValueNode) is the generic, byte-faithful
//! value: `;`-separated components of `,`-separated leaves.
//!
//! [`IcalValueCursor`](cursor::IcalValueCursor) reads and writes it through
//! the codec, escaping on write and preserving every component it does not
//! touch. What the components *mean* is the lens's business (see
//! [`crate::tree::prop`]).
