/* ═══════════════════════════════════════════════════════════════════════════
   EduCare — Landing page publik (www.educare.id)

   BERDIRI SENDIRI. Berkas ini sengaja TIDAK memakai tailwind.css/application.css
   milik aplikasi, karena keduanya mengunci html & body ke
   `height:100%; overflow:hidden` demi app shell sidebar-tetap
   (lihat docs/TABLE_STYLE.md §1) — halaman panjang seperti ini tidak akan bisa
   di-scroll di bawah aturan itu.

   Nilai warnanya DISALIN dari palet aplikasi (app/assets/tailwind/application.css)
   supaya landing page dan panel terlihat satu produk. Kalau hue brand diganti di
   sana, ganti juga --brand/--brand-bright/--brand-soft di sini.

   Semua prefiks kelas `lp-` (landing page) agar tidak mungkin bentrok dengan
   kelas aplikasi kalau suatu saat kedua stylesheet dimuat bersamaan.
