/* Tezaur sau Fidelis
   A ledger palette: cream paper, a state-treasury teal for Tezaur, a market-copper for
   Fidelis, and a separate semantic green/rust pair for real (inflation-adjusted) return
   that stays independent of which program is selected. Both themes declared here in full;
   no colour is written outside a token block. */
