//! # PHOTO lens
//!
//! Reading and editing the `PHOTO` property in place.
//!
//! Its value shape is version-specific, so the lens overrides
//! [`decode`](VcardPropLens::decode) to resolve it from the card version
//! through the property spec: a `data:` URI in 4.0 ([`VcardValue::Uri`]),
//! inline base64 or a URI reference in 2.1 / 3.0 ([`VcardValue::Binary`]).
//!
//! Its RFC contract sits on the marker, [`PHOTO`].
