   Paper  = ivory envelope tile (paper-tile.webp, 708×1268 CSS px repeat, base #F0ECE6)
   Ink    = burgundy #5C1A1E (headlines, wordmark, active), deep #3E0F14

   Rules  = burgundy 30% (letter rules, ornaments) · espresso 13% (row dividers)
   Type   = Bodoni Moda (OFL Didone): wordmark, Latin display, tracked labels
            Noto Serif KR: the voice (body, letters, all Korean headlines)
            Pretendard: UI (nav, links, footer)
   Seal   = only at thresholds: hero flap tip + footer colophon. Never on burgundy.
