Research direction
Start with the mandatory reproducer and run it with yarn android on Android, comparing the visible text with the Text props. Trace the Fabric Android Text rendering path for the flexDirection: 'row', font size, line height, and bold styling shown in the issue. Done means the full VERIFY NUMBER text remains visible in the reproducer.
