[Key Highlights & Architecture]

• One-Tap Automated Login Engine: Automatically coordinates multi-step forms (National ID, ROC birthdate, mobile number) and handles Spring Security CSRF tokens in the background to ensure effortless sessions.
• Family Vault & Hardware Security: Encrypts personal credentials exclusively on-device using secure hardware enclaves (Keychain / Keystore via expo-secure-store), backed by biometric authentication (Face ID / Fingerprint). No personal data is ever sent to third-party servers.
• On-Device OCR Pre-check: Validates workout proof screenshots locally (step count, date format, distance) using embedded Tesseract OCR before official submission, drastically reducing rejection rates.
• 14-Week Countdown & Partner Perks: Real-time countdowns for weekly fitness goals and aggregated redemption bonuses across 5 major sports retail channels.
