/* THE NICK.EXE CASE FILE — design system
   Three visual languages, one per epistemic status:
   - EVIDENCE  : pale, document-like, cyan-edged
   - LORE      : green phosphor terminal
   - INTAKE    : amber, machine-stamped, unreviewed
   Palette nods to nick.exe's CGA art: cyan / magenta / yellow on black. */
