See it actually work.

A real screen recording — Chromium with the extension loaded, filtering a Netflix-style catalog. The catalog is padded with a Kids & Family row; one click sets a 14+ floor and that whole row disappears while the grown-up rows stay. Then the floor is tuned higher, and switched to “dim” mode.

Note: RatingFloor runs on the real Netflix; this demo uses a representative Netflix-style catalog so it can be recorded without a personal login — but every frame is the genuine extension doing the genuine filtering.
