   The name reads as "trust", and trust is something you can only demonstrate
   by keeping a record. So the whole surface behaves like a ledger: ruled
   lines, entry numbers, and commitments that get signed and timestamped.
   Palette: oxblood velvet + gold leaf. No white page, no beige, no blue.
