 ## 2024-05-24 - Enhancing Inputs Safely
 **Learning:** Adding features like character counters to generic input components must handle both controlled and uncontrolled states. Assuming a component is controlled (using `props.value`) can break uncontrolled usage by showing stale data (e.g., sticking at 0/100).
 **Action:** When enhancing generic components, detect uncontrolled state (e.g., `props.value === undefined`) and either implement internal state tracking or gracefully degrade (hide the feature) to avoid misleading UX.
+
+## 2025-02-14 - Skip to Content Implementation
+**Learning:** Implementing a "Skip to Content" link requires not just the link component, but ensuring the target `<main>` element has `tabIndex={-1}` and `outline: 'none'` (or CSS equivalent) to ensure programmatic focus works correctly without creating an ugly focus ring on the container.
+**Action:** When adding skip links, always verify the target container's focusability and visual focus style.
