//! `SimpleContentLog` — on-disk shape of [`super::SimpleContent`].
//!
//! Parallels [`super::RichContentLog`] (post-rewrite): every chunk is
//! a [`LogReference`] to its own `.txt` file. No inline content.
//!
//! Two variants, matching `SimpleContent`'s untagged Text/Parts split:
//!
//! - `Reference` — the message had a single
//! [`super::SimpleContent::Text`] payload; that string was written
//! to one `.txt` file and we hold the reference.
//! - `Parts` — the message had a [`super::SimpleContent::Parts`]
//! payload; every part (always
//! [`super::SimpleContentPart::Text`]) was written to its own
//! `.txt` file and we hold one reference per part, in original
//! order.
//!
//! On the wire (untagged-distinguishable: object vs array):
//!
//! - `Reference`: `{"type":"reference","path":"…/text/abc-0.txt"}`
//! - `Parts`: `[{"type":"reference","path":"…"}, …]`
