Summary

• add an inset “Private by design” passport card at the top of Data and About
• state the privacy model directly: location history stays on the user’s devices and in their private iCloud account, and Where sends no data to anyone
• render the privacy card as a passport-navy, gold-accented reflective surface using the location cards’ snapshot- and Reduce Motion-aware tilt treatment
• keep the security-print rosette and Liquid Glass treatment independent from motion availability, so the complete surface remains visible before or without a tilt sample
• share the passport-card structure with the GitHub link while retaining standard Form insets and the native two-shadow treatment from main; the privacy variant uses a quieter dark-navy glow
• cover the complete Data and About pages with intrinsic-size iPhone and iPad snapshots across appearance, contrast, and accessibility variants

Testing

• ./test WhereUITests (354 tests passed before the visual follow-ups)
• focused PassportCardSurfaceKindTests, PassportCardSurfaceTests, PassportCardTests, PrivacyPassportCardTests, and passportCardStyle tests
• focused AboutSettingsViewSnapshotTests and DataSettingsViewSnapshotTests
• ./swiftformat --lint
• ./xcstrings --lint
• swift run bumper lint . --timings
