/**
 * Stravum Popup — smooth open/close transition.
 *
 * The overlay stays in the DOM at all times (never display:none, which can't
 * be transitioned); popup.js toggles a single .is-open class and CSS handles
 * the fade + panel scale-in/out. visibility is delayed on the way OUT (so the
 * overlay stops intercepting clicks only after it's fully invisible) and
 * instant on the way IN.
