/* ============================================================
   HALAMAN KALKULATOR BPHTB — diselaraskan dengan landing page.
   Palet Emerald & Gold mengambil variabel --lk-* yang didefinisikan
   di landing-kayong.css (file tersebut ikut di-load halaman ini).

   Halaman ini sengaja TIDAK memuat Cuba admin CSS (bootstrap.css,
   style.css, responsive.css) karena Bootstrap 5.0.0-beta di sana
   di-load terakhir dan menimpa Bootstrap milik front theme —
   itulah sumber tampilan "admin" yang tidak senada.
