Observed 42 client samples across 21496ms: all raised-surface counts = 1, all composer matches = 1.
Neighbor checks: light appearance = 2 painted composer layers; text inspection = 17 uses; editing raised surface hex updates actual ::before paint; clearing selection and closing editor remove highlights.
Main baseline 6575ce3250: visible composer, raised surface = 0 uses.
