/* ============================================================
   Flaming fleet — Landing kit (logged-out `/`)
   Source: FlamingTracker tracker/app/templates/landing.html (2026-09-25),
   corrected to DESIGN-SYSTEM.md §4 (nav + header auth rules), §5 (footer),
   §7 (buttons/cards) and §11 (skeleton, 4/2/1 feature grid).

   Every class is prefixed `lk-` so this file can load next to any site's own
   stylesheet without fighting over `.btn`, `.hero`, `.card`, `.footer`.
   Every token has a fallback, so it renders correctly with no site CSS at all.
