/* Epilogue — "Paper & Marquee" design system.
   A warm paper-light app with one dark room in it: the quiz plays in theater
   dark, and every book-facing screen lives on cream paper. Fraunces is the
   voice; Instrument Sans is the operator. Marquee red belongs to money and
   nothing else. Body floor is 16px; nothing recurring ships under 14px. */
