## Summary
Refresh mobile onboarding with light/dark gradients, an animated fuzzy
Buzz wordmark and tagline, and bottom-aligned glass/ghost actions.
Remove the dot grid and idle scroll bounce, and smooth the QR scanner's
continuous corners and spring transitions by deferring camera teardown
until dismissal finishes.
### Related issue
