   THE ROGUE PATIENT - BRAND TOKENS
   V1.2, 2026-10-21

   SOURCE OF TRUTH: the founder's own selections, read back from the saved
   decision records on 2026-10-21.

     Type Round 2 (decisions/type-round2)      Instrument Serif ticked
     Masthead Mock (approved by screenshot)    Instrument Serif
                                               All caps: on
                                               Hard shadow: on
                                               Headlines in same face: on
     Masthead Mock palette                     paper #F5EEE3, card #FAF6EE,
                                               ink #121211, crimson #990000,
                                               slate #1E293B, gold #FACC15,
                                               rules black, 3px, hard offset

   Body text is Libre Baskerville, the reading face in the approved mock.
   Labels and small furniture are Inter. Nothing here comes from the
   Substack theme; that reading (V1.1, Spectral on white) was wrong.
