/* tutor.css — the Cockpit Tutorials player (story-format animated tours), 2026-10-09.
   Hook-in: zero app.js / styles.css edits. Everything is themed from the site's own tokens
   (--bg --panel --text --muted --accent --bull --bear --amber --border) so the 18 skins and
   light/dark carry through. Only transforms and opacity animate; the vibe canvas is blurred
   statically. prefers-reduced-motion: no keyframe animation at all. */
