- right.rs: drop the unused ACCENT import (main removed it); keep the grid
constants CAPTION_PT/TEXT_PT/TITLE_PT our branch added.
- typography.rs: keep our TEXT_PT size, adopt main's accent_text token rename.
- widgets.rs: keep our TEXT_PT size for the button label; the disabled colour is
now main's text_tertiary from the match, so the old dim() closure is dropped.
- ui-parity.md: keep our row and main's two (#890, #894) changelog rows.
