Workout Completion Overlay

Added an animated overlay shown at the end of each workout before revealing stats. Displays a badge with confetti, a motivational message, and auto-dismisses after 3.5s (or on tap). The message adapts based on the user's efficiency score:

• < 20% efficiency — "Good job / You Showed Up" — encourages consistency over perfection

• 20–89% efficiency — "Well done / Crushed It" — acknowledges a solid effort

• ≥ 90% efficiency — "Well done / Legendary Session" — recognizes near-perfect performance

Includes a progress bar at the bottom indicating time until auto-dismiss. Fully translated across all supported languages.

Device-Specific Orientation Video

The accelerometer setup step now shows a laptop-specific instructional video on desktop devices instead of the phone video. Mobile devices continue to see the original phone video. Both the preloader and the orientation section detect the device type and load the correct asset.
