[Bug]: Improve Frontend Accessibility (A11y)

**App Name:** `web`

**Describe the bug**
The frontend application likely has accessibility issues that hinder users with disabilities (e.g., lack of keyboard navigation, insufficient ARIA attributes, poor color contrast).

**To Reproduce**
(This would require specific steps for each identified A11y issue, but for the general issue, it's an audit)
1. Use a screen reader to navigate the application.
2. Attempt to use the application solely with keyboard navigation.
3. Use a color contrast checker on various UI elements.

**Expected behavior**
The application should be fully navigable and usable by individuals with disabilities, adhering to WCAG guidelines.
