Struct Fixture 

pub struct Fixture {
    pub raw: &'static str,
    pub impermissible: &'static [&'static str],
}

One eval case: a phrase + substrings a faithful cleanup must never introduce. Fixtures are written already pre-processed (no spoken commands) so they isolate the formatter’s restraint, not the deterministic pre-layer.

raw: &'static str
