Test instructions

• Use a default FSE theme (Twenty Twenty-Five should be ok).
• Edit the archive page in the full site editor.
• Editor: select text → Dynamic Value → Archive Title → confirm a "Remove Title Prefix" toggle appears in Settings.
• Frontend: place Archive Title on a category archive with the toggle on → shows term name only, no Category:.
• Regression: toggle off → prefix returns (Category: …); the Before/After fields still apply on top.
• Coming to this version from a previous one without the toggle should still work as expected.
