/* Letters to the Future — the ONE letter card (letter/cards.js, 2026-10-20). Loaded by Home
   (app/index.html) and the letters page (letter/index.html), so the card looks the same in both:
   white, the envelope on the left, who it's for, one line in words and the Written · Confirmed ·
   Delivered track, whose last stretch fills with the share of the wait already behind it.
   Self-contained: its own colours, only tokens.css's ink and faces from outside. */
