 ## 2025-06-17 - [Accessible Checkboxes and Consistent Prop Spreading]
 **Learning:** Enhancing base form components like `CustomCheckbox` with standardized `required` indicators (visual asterisk and `aria-required`) and grid support (`s`, `m`, `l`, `xl`, `offset`) improves both accessibility and developer productivity. Ensuring that `...props` are consistently applied to the inner `input` regardless of the presence of a wrapper `div` maintains a predictable component API.
 **Action:** Always provide visual and semantic cues for mandatory fields and ensure consistent prop-spreading behavior in multi-layered components.
+
+## 2025-06-27 - [Semantic Form Submission, Label Associations, and Radio Button A11y]
+**Learning:** Wrapping input fields inside a semantic `<form>` element restores native browser submit support, enabling keyboard navigation and Enter key submissions. When designing list/grid-based form inputs (like question option fields), ensuring each input has a corresponding `<label>` (rather than only a placeholder) prevents the label from disappearing when users start typing. Additionally, using descriptive `aria-label` and `title` attributes on associated radio buttons improves screen reader compatibility. In Playwright, custom styled layouts may intercept pointer events, which can be bypassed using `click(force=True)` to directly trigger the radio button input.
+**Action:** Always wrap interactive form sections in a `<form>` element, strictly enforce ID/htmlFor label-input associations, and write robust Playwright selectors using `force=True` when layouts trigger pointer-event overlaps.
