MOBILE: Guidance message text floats over camera with no background — near-zero contrast on bright scenes

[pnsw123]

File: /src/components/MobileCaptureScreen.tsx line 767.

Guidance text floats over live camera feed with only drop-shadow-lg for contrast. On bright scenes (user following instruction to use flashlight), white text on light background has near-zero contrast.

Fix: Add semi-transparent dark pill background to guidance message:

className="bg-black/50 backdrop-blur-sm rounded-full px-4 py-2"

Ensures legibility in all lighting conditions.
