From the theme sweep review, three overarching light-theme fixes:
- Buttons: bump ImGuiCol_Button light overlays 13/20/28% -> 16/23/30% so the
small/secondary buttons read as clearly as the main ones.
- Dividers + outlines: raise --divider (0.12-0.14 -> 0.20) and --outline
(-> 0.24) across all light skins so section/list dividers are visible on white.
- Ratio/balance bars: deepen the muted --success/--warning greens/ambers in the
light skins that were pale (light, marble, dune) so the shielded/transparent
bars + success text are vivid (color-pop-light + iridescent were already vivid).
