描述

The v1 side-nav is missing focus trapping, so it's currently possible to tab out of the drawer and into the background content, while it's open. We should implement focus trapping to prevent that from happening.

研究方向
Focus trapping prevents keyboard focus from leaving an open drawer. In this issue, the side nav drawer lacks focus trapping, allowing users to tab out. To implement, first locate the side nav component (likely in side nav.js or related files). Study the drawer's open/close logic. Use a common focus trapping pattern: when drawer opens, save the last focused element; intercept Tab key events within the drawer; loop focus among tabbable elements inside. Ensure the trap releases on close. Check for any existing discussions or PRs that attempted this (none currently). After implementing, test manually with keyboard navigation.
