/* =========================================================
   Landing page — the public front door, in the same design system as
   the learner pages (see echospell_ui.css): a dark hero with depth,
   then a warm workspace of cards that lift in 3D.
   Loaded after landing.css, which still owns the moving parts that
   landing_motion.js drives (word cycling, transcription write-on,
   reveal-on-scroll, drifting symbols, the ribbon). Class names those
   rely on are kept; this file restyles around them.
