/* ============================================================
   syntax.css — Chroma highlighting palette for Course Code
   "The Almanac" (Signal). Kept low-contrast so code sits
   quietly in prose. Most posts are untagged shell one-liners
   (no token classes) — those are styled by `pre` in
   digital-archivist.css; this file only colors the tagged
   minority. Class names are Chroma defaults.
   Hugo: set pygmentsUseClasses = true in config.
