//! The binary form — self-describing, compact: what a build compiles
//! content to, what saves and caches are kept in, what a reader that
//! doesn't know the schema can still walk. `docs/format.md` ("Binary form")
//! has the layout: a header (`SDAT`, a version byte), then the root value,
//! a tag byte and its payload. A string is written where it's first used
//! and referred to after that, so repeated keys and ids cost one varint
//! each and the writer never goes back over what it wrote.
//!
//! Nothing is aligned, and decoding checks every length against the
//! input, so malformed bytes are an error, never a panic or a huge
//! allocation. A [`crate::Schema`] writes itself here straight
//! ([`crate::Schema::encode`]) and reads itself back the same way
//! ([`crate::Schema::decode`]) — no value tree on the way.
