/* ============================================================
   SIGNAL — article reading layout (shared by all dispatches)
   Warm paper, deep green-ink, restrained sage. The signature:
   metadata set in JetBrains Mono with a "SIGNAL" chip, framing
   each piece as a transmitted dispatch from the lab rather than
   a generic blog post. Boldness is spent here and on the single
   "stance" line per article; everything else stays quiet.
