//! One window of a stored Markdown version, laid out as blocks
//! (`crates/wire/spec/Answer/Preview.lean` ยง8-74).
//!
//! Read by the version, for the reason a range is: a page previewing a
//! file a resident is rewriting goes on reading the version it opened.
//! The blocks are the `documents` crate's grammar, carried as it spells
//! them (`crates/documents/Spec.lean` D1, D21); `Laid.span` says which
//! stretch was read, which is where the next request starts from.
