   Southern AI Systems — Blog index styles (Graphite)
   Loaded by /blog/ index only; article pages use sais-ds.css alone.

   Retokenized 2026-08-23 to the Graphite system (white/ink, Inter Tight +
   JetBrains Mono via sais-ds.css, no accent hue). The earlier violet palette
   and the Plus Jakarta Sans / Newsreader pairing referenced a site generation
   that no longer exists — those fonts were never even <link>ed, so they always
   fell back. Accent slots below intentionally resolve to ink/gray.
