   THE BURROW — Franz Kafka voice model · landing page
   House base: The Elect terminal-grimoire aesthetic
   Persona register: paper-and-ink · bureaucratic dossier ·
   late-night letter. NOT fire — institutional dread, dim lamp.

   Two-mode design is the hero:
     · "the man"  → ink-blue (the late-night letter)
     · "the work" → sepia/ochre (the dossier, the file)

   Accessibility baked in: every text color computed ≥4.5:1 AA
   on its background (≥3:1 for large headings). Portrait calmed
   to opacity 0.8 with a soft cool tint so it reads as a portrait.
