Localized home pages (/es, /fr, /de, /it, /pt) with server-rendered intro,
how-to-play and FAQ plus FAQPage/WebApplication JSON-LD and hreflang.
Puzzle archive at /archive with answer pages (/puzzle/N) for past days only
and replays (/play/N) that never touch stats or the daily streak.
Challenge loop: shared results link back as /?challenge=<code> and the result
screen shows a head-to-head verdict.
Also adds robots.txt, sitemap.xml, the PWA manifest and icons, a compact
share text with WhatsApp/X/copy channels, a next-puzzle countdown, the
social-proof play counter and a spoiler-free /api/teaser for daily posting.
