   Plain CSS, no build step. Loaded from resources/views/basic.blade.php.
   --------------------------------------------------------------------------
   The palette comes from the logo: seven figures ringing a broadcast tower.
   Those seven are used as marks and signals, not as full-width washes — a
   page of tinted blocks read as decoration rather than as structure.

   Type: Newsreader (display), Atkinson Hyperlegible (body — drawn for
   low-vision readers, which earns its place on a mental health site),
   IBM Plex Mono (register: counts, grant ids, labels), Noto Serif Bengali
   (the blog is mostly Bangla and was falling back to a broken face).
