Three matched fixes — same patterns shipped on OnboardingWizard,
ConfirmDialog, ApprovalBanner.
1. 4× bg-accent-strong hover:bg-accent (Save, Add, two Show buttons)
hovered LIGHTER on white text — accent is the lighter variant, so
contrast dropped below AA on hover. Flipped: bg-accent
hover:bg-accent-strong.
2. 4× bg-surface-card hover:bg-surface-card no-op hovers (Collapse,
Open, Hide-Advanced, Refresh, Cancel). Lift to surface-elevated
so the buttons visibly respond.
3. Delete row button: text-bad hover:text-bad was a no-op. Switched
to a light hover bg + focus-visible danger ring so the destructive
action visibly responds and keyboard users see focus.
