   "The Field Journal" — an editorial curiosity-atlas identity built to
   sit outside every competitor cluster we studied:
     - not dark-neon-purple AI app (WigglePet / Singing Pet)
     - not mint clean SaaS (DreamFace)
     - not warm terracotta retreat serif (Yang Mun / Yang Muns)
   Instead: warm ink + paper, one restrained brand ember accent, and a
   distinct accent per universe, unified by a shared "volume / field
   note" card language (index tabs, hairline rules, torn-corner frames).
