// Regression guard: provider cards must have a *visible* hover state.
//
// Reported bug: hovering a provider card made it go "transparent / not
// highlighted". Root cause was a 1%-opacity hover (`hover:bg-black/[0.01]` /
// `hover:bg-white/[0.01]`) — effectively invisible. The fix switches both card
// surfaces to the dashboard's dominant, visible hover (`hover:bg-*/5`) plus a
// `hover:border-primary/40` highlight. This pins it so the near-invisible hover
// can't silently come back.
