/**
 * Click-Proxy Navigation for ct-has-link-overlay
 *
 * Accessibility Notes:
 * - Keyboard users are unaffected because the actual <a> elements remain focusable
 *   and receive keyboard events normally (Tab, Enter, Space)
 * - Screen readers still announce links correctly because the DOM structure is unchanged
 * - The .ct-link-overlay anchor has pointer-events: none but is still in the DOM
 *   for screen reader discovery
