/* =============================================================
   tutorialEngine.css — single shared visual layer for every
   tutorial in the game (see scripts/tutorialEngine.js).

   Two modes share these styles:
   - "blocking" mode (#ob-backdrop / #ob-tut-popup / #tutorial-cursor):
     persistent 4-panel cutout + Skip popup + hand cursor, used by the
     main gameplay onboarding flow (it ticks every frame and physically
     blocks stray taps outside the highlighted target).
   - "dim" mode (.tut-overlay / .tut-hole / .tut-label / .tut-arrow /
     .tut-click-indicator): a lightweight one-shot highlight used by
     every contextual tutorial (galaxy, boss, companions, cosmetics...).
     Non-blocking — pointer-events:none, the real click underneath both
     dismisses the tutorial and performs the real game action.

   .ob-spotlight (the pulsing highlight ring) is shared by both modes.
