/* ============================================================================
   WordSeek — cute pastel "panda" theme
   Performance notes:
     - No JS animation libraries; all motion is CSS transform/opacity/filter.
     - Only 4 blurred blobs + 3 toy shapes as ambient (no particle canvas).
     - Confetti is on-demand only. Small DOM, one webfont family.
   Sections:
     1. Tokens   2. Reset/base   3. Background   4. Layout   5. Top bar
     6. Hero + panda mascot   7. Cards   8. Input   9. Results
     10. Side panel   11. Footer   12. Toasts   13. Modal
     14. Keyframes   15. Responsive   16. Reduced motion
