 ## 2025-05-14 - Tooltips for Icon-only Buttons
 **Learning:** Icon-only buttons, while space-efficient, can be ambiguous for users who rely on visual cues but don't immediately recognize the icon. Providing a Tooltip alongside an ARIA label ensures both visual and screen-reader accessibility. In HeroUI v3, the `Tooltip` component should wrap the interactive element, using `Tooltip.Trigger` and `Tooltip.Content` for clarity.
 **Action:** Always wrap icon-only buttons in a Tooltip if the action isn't globally standard or if additional clarity can be provided without cluttering the UI.

+## 2025-05-15 - Micro-UX Polish: Focus and Snappiness
+**Learning:** High-contrast focus rings (`focus-visible:ring-primary`) significantly improve navigation for keyboard-only users. Additionally, reducing Tooltip delay from 300ms to 200ms makes the interface feel noticeably more responsive and "snappy" without becoming distracting.
+**Action:** Apply consistent `focus-visible` styles to all interactive elements and standardize Tooltip delays to 200ms across the application.
