//! The keymap table (0008 §3 — keymaps as data). v1: this table drives
//! the `Space ?` keybinds popup and the which-key prefix cards; the trie
//! dispatch cutover (0008 §5) makes it the dispatch source later.
//!
//! Coverage contract (0003 §5.7): every dispatchable binding renders in
//! the popup; the tests below pin both directions. `live: false` rows
//! are planned slots — reserved keys with no dispatch yet (0003 §6) —
//! and render muted with a "(soon)" suffix, never as live bindings.
//!
//! ## Notation
//!
//! `keys` is space-separated tokens, one key per token (`esc`, `:w`,
//! `"+y`; `<a>`/`<c>` parameterize a char):
//!
//! - `space` is the leader: its sequence runs to the row's end.
//! - `ctrl-w` takes exactly one following key.
//! - ` / ` separates alternatives that replace the last key of the
//!   sequence before them (`space d / k` → `space d`, `space k`);
//!   alternatives run to the row's end.
//! - Every other token is one single-key sequence; a row may list
//!   several (`h j k l`), and a leading bare `/` is the search-forward
//!   key (`/ ?`).

/// How a sequence dispatches (0008 stage 2). The walker consults these;
/// `?`/which-key read the same row — the table is the single source.
