This pull request improves accessibility in the browser example by replacing invalid tags with styled

| ## 2024-05-22 - Replacing invalid label tags | ||
| **Learning:** In HTML, `<label>` tags are strictly reserved for labellable form controls. | ||
| **Action:** To make scrollable, non-interactive generic containers (like `div`s with `overflow-y: auto`) accessible, use a styled `div` for the text label and link it to the container via `aria-labelledby`, while ensuring the container has `tabindex="0"` and `role="region"`. |

While recommending role="region" is helpful for landmark navigation, it should be noted that this role is best reserved for significant sections of a page. Overusing landmarks can lead to a cluttered experience for screen reader users. Consider qualifying this advice to ensure it is applied to meaningful content areas rather than every scrollable container.

The display: block and margin-bottom: 0 styles are redundant for a div element in this context. div is a block-level element by default and carries no default margin in this project's stylesheet. Removing them simplifies the code while maintaining the same visual appearance.

The display: block style is redundant for a div element, as it is block-level by default.

💡 What: Replaced invalid
<label>tags pointing to non-interactive, scrollable<div>containers with styled<div>s linked viaaria-labelledby, and addedtabindex="0"androle="region"to the containers.🎯 Why:
<label>tags are strictly reserved for form controls. This change improves accessibility by properly labeling scrollable regions and making them keyboard-navigable for screen readers.📸 Before/After: Visual appearance is maintained, but semantic accessibility is improved.
♿ Accessibility: Improved keyboard accessibility and screen reader support for output containers by using
role="region",aria-labelledby, andtabindex="0".PR created automatically by Jules for task 5928624545372644310 started by @EffortlessSteven
