/* ── Blok "Timeline" (page-builder) ──
   Tiga model memakai markup yang SAMA, hanya beda class di wrapper:
     .bk-tl-alternate  → garis di tengah, kartu zig-zag kiri/kanan
     .bk-tl-line       → garis di kiri, semua kartu di kanan
     .bk-tl-horizontal → jalur horizontal yang bisa digeser (scroll-snap)

   Warna (aksen, garis, latar kartu, teks) datang dari color picker admin dan
   ditulis inline sebagai background-color / color / border-color — properti
   yang lolos HtmlSanitizer. Garis penghubung TIDAK pakai ::before (warnanya
   tidak bisa di-inline), tapi elemen <span class="bk-tl-seg"> per item yang
   menyambung dari node item ini ke node item berikutnya. Semua bentuk lain
   (radius, posisi, shadow, transisi) wajib di sini karena dibuang sanitizer
   kalau ditulis inline. */
