🚨 Severity: HIGH 💡 Vulnerability: Weak master password requirements allowed short or simple passwords, reducing security of encrypted data. 🎯 Impact: Brute-force attacks on encrypted localStorage data are easier with weak passwords. 🔧 Fix: - Increased minimum password length from 8 to 12 characters in UI validation. - Added a complexity requirement of at least 4 unique characters for new passwords. - Implemented defense-in-depth in the cryptographic layer to enforce an absolute minimum of 8 characters. - Centralized password length limits in `lib/constants.js`. ✅ Verification: Verified with Playwright script showing error messages for short and simple passwords, and successful build with `npm run build`.

This security enhancement strengthens the protection of user data by enforcing more robust master password requirements. It implements a tiered approach: the UI now requires a 12-character minimum with a complexity check (4 unique characters) for new setups and password changes, while the cryptographic layer maintains a defense-in-depth minimum of 8 characters to preserve backward compatibility for existing users while preventing future weak entries. All limits are centralized in the
