- Implements a `keydown` listener on the modal to intercept Tab and Shift+Tab key presses.
- Dynamically queries visible focusable elements (`button`, `input`, etc.) that have a valid `offsetParent`.
- Loops focus between the first and last focusable elements to prevent keyboard users from tabbing out of the modal into obscured content.
- Enhances accessibility for screen reader and keyboard-only users.
