1//! Paired-container classifier tags.
2//!
3//! [`ContainerKind`] is the tag the lexer's classify phase emits on
4//! every paired open / close marker (e.g. `［＃ここから2字下げ］ … ［＃ここで字下げ終わり］`).
5//! The renderer reads it when wrapping the enclosed sibling nodes
6//! into an `AozoraNode::Container`.

8/// The kinds of Aozora container blocks the lexer classifies.
