   Identity: "The Ledger & The Letter"
   Two voices with a hard boundary:
     — the LETTER: serif prose (Source Serif 4)
     — the LEDGER: monospace data (IBM Plex Mono)
   UI chrome (nav, labels, buttons): Inter.
   Palette (4, never more): paper, ink, grey, rust.
   No dark mode. No decorative motion.
