/* ==========================================================================
   Vaytax. Letter-read demo motif (2026-07-16).
   Shows a German Finanzamt letter being read into English, before the visitor
   uploads anything. Mounted by letter-demo.js into [data-letter-demo].
   Tokens borrowed from the host page (same set letter-decode.css uses):
     --primary --primary-dark --gold --cream --border-soft --paragraph
     --body-text --font-ui --font-mono. Fallbacks inline so it can also sit on
   pages that define fewer tokens (e.g. the homepage).
   Motion follows the house pattern (product/amazon-fba): elements are visible
   by default; JS adds .ld-animate to opt INTO the reveal, so no-JS and
   prefers-reduced-motion both land on the full static composition.
