Today every sublayer style bag stores sizes in screen pixels (constant-on-screen behaviour the user asked for in the 2026-05-25 conversation). The seam is preserved: every size field reads through a SizeUnit so adding MapUnits later is localised to the renderer.

Cross-slice: Slice S1 (sublayer foundation). Consumed by every ISublayer style bag.
