/* ============================================================
   MAREGRAPH — almanac shell
   Bukan terminal ber-sidebar: ini lembar almanak pasang-surut.
   Header dek horizontal, hero serif di tengah, laut melintang
   selebar halaman di bawah, dan halaman men-scroll secara
   native — tidak ada shell yang dikunci.

   Satu tinta, kertas bergaris (bukan grid titik), aksen teal.
   Serif untuk judul, mono untuk data.
