/* Popup sambutan LOGIN/DAFTAR (.popup). Muncul saat halaman dimuat; ditutup lewat
   /js-assets/template/article-modal.js (Escape, klik latar, tombol tutup).

   GAYA mengikuti template-kompas/css-assets/components/popup.css: kartu ungu-gelap
   bergradien, garis aksen neon di tepi atas, badge "Resmi" berdenyut, dua tombol
   (Daftar = gradien ungu, Login = ghost). Warna dari token --c-* di
   /css-assets/base/tokens.css. Yang tetap "versi Envato": tipografi memakai
   PolySans (token --font-family-*), dan animasi masuk memakai keyframes
   popupOverlayIn/popupShow/popupItemIn/popupCtaSheen dari base/animations.css.

   Struktur: .popup (overlay) > .popup__card > __close, __media (__img, __badge),
   __body (__eyebrow, __title, __text, __actions, __note), __footer */

/* Overlay.
   Overlay ini sekaligus menjadi KONTAINER SCROLL modal: pada viewport pendek
   (mis. 844x390 lanskap) isi popup lebih tinggi daripada layar. Dengan
   align-items:center kelebihan tinggi terpotong di SISI ATAS dan tidak bisa
   digapai. Maka: flex-start + overflow-y:auto, dan pemusatan vertikal
   diserahkan ke `margin:auto` pada kartunya (hanya memusatkan bila muat). */
