   Warna aksen/garis/latar ditulis INLINE (lolos HtmlSanitizer); bentuk,
   posisi & hover di sini (border-radius, position, :hover dibuang kalau inline).

   Model:
     .bk-tl-alternate  Model 1: zig-zag, garis di tengah (≥ 768px).
                       Di < 768px berubah jadi satu sisi dengan garis kiri.
     .bk-tl-line       Model 2: garis di kiri.
     .bk-tl-horizontal Model 3: geser ke samping (overflow-x + scroll-snap).
