## What - add the shared desktop-style arc spinner for mobile - replace app loading indicators with the shared component - preserve a static pose when reduced motion is enabled ## Stack - follows #3313 ## Validation - `just mobile-check` - focused spinner and pairing widget tests --------- Signed-off-by: kenny lopez <klopez4212@gmail.com>
