9/// What pressing a [`ButtonId`] should do.
10///
11/// Serialization uses serde's default external tagging: unit variants
12/// serialize as a bare string (`"BrowserBack"`) and the tuple variant
13/// serializes as a single-key table (`{ CustomShortcut = "my chord" }`).
14///
15/// **Stability contract:** existing variant *names* are frozen — they form the
16/// on-disk `config.toml` schema. New variants may be appended freely; removing
17/// or renaming a variant requires a `schema_version` bump and a migration.
18///
19/// This type is pure config data: OS-level event synthesis for each variant
20/// lives in the `openlogi-inject` crate (`openlogi_inject::execute`), keeping
21/// this crate platform- and IO-free.
