+**Phrase removal can expose a leading space that matches other phrases** —
+`knownRemovablePhrases` does a plain substring replace with no post-trim. If you
+add `"Foo Bar:"` and the title is `"foo bar: uncut gems"`, removing `"foo bar:"`
+leaves `" uncut gems"`, and a phrase like `" uncut"` (with a leading space) will
+then match, producing just `"gems"`. The fix is to include the trailing space in
+the phrase: `"Foo Bar: "`. Do this whenever the phrase is always followed by
+more content (i.e. it is a prefix label, not a suffix or mid-title fragment).
