   Thai text uses CUFTM's fonts (Anuphan → IBM Plex Sans Thai).
   English: MuseoModerno for headlines, Jost (a Futura-style face) for text.
   To use licensed CI fonts later, drop the files in /public/fonts and add
   @font-face rules — the stacks below already fall back gracefully.

     Both are commercial and are NOT bundled with this project. They are named
     first in each stack, so anyone who has them installed — and the site
     itself, once licensed .woff2 files are added — gets the real CI faces.
     See public/fonts/อ่านก่อน.txt for how to switch them on.

     Until then the site uses two free stand-ins chosen to match:
       Mitr (Cadson Demak) — loopless and geometric, like ArchTH, and built to
         sit beside geometric Latin such as MuseoModerno
       IBM Plex Sans Thai Looped — a modern looped text face, the same category
         as Thonglor, and readable at small sizes */
