/* The Topper's Mindset — shared styles for the hub and every lesson.
   One file so a new lesson only has to write its slides.
   Modes (set on <html> by reel.js):
     .reel       phones and small tablets: full-screen vertical swipe, like Reels
     .presenting full screen in class (any device that supports it)
     .card-mode  renders one slide as a share image (used by tools/share-cards.py) */
