/**
 * PageExitTrigger
 *
 * Triggers timeline playback when a user clicks a link that would navigate away
 * from the current page. Intercepts the click, plays the exit animation, then
 * navigates to the target URL after the timeline completes.
 *
 * Supports three link selection modes:
 * - 'all': intercept all navigation links (default)
 * - 'include': only intercept links matching specific selectors
 * - 'exclude': intercept all links except those matching specific selectors
 *
 * Supports skipping certain href patterns:
 * - 'anchor': skip # links (same-page anchors)
 * - 'javascript': skip javascript: hrefs
 * - 'mailto': skip mailto: and tel: hrefs
 *
 * Works on all websites — no server-side dependencies (PHP, Node, etc.).
