What's New in v2.0

The biggest update since launch — a complete visual and architectural overhaul.

Major Features

• Collapsible Sidebar — smooth animation, avatar always visible, tooltips when collapsed
• Light Mode — with confirmation modal before switching (dark mode still default)
• Habit Repeat — auto-copy habits from previous month, analytics-aware createdAt field
• Install App — Android native install prompt + iOS instructions modal
• Offline Support — service worker with embedded offline page, network-first strategy

Security & Auth

• Switched from reCAPTCHA v2 to hCaptcha (works in Brave & privacy browsers)
• Removed DNS MX lookup for disposable email detection (was causing CSP violations)
• Firestore security rules hardened — ownership checks, doc size limits, field validation
• Generic error messages for auth failures (prevents user enumeration)
• Removed App Check and Cloud Functions (Spark plan compatibility)

UI/UX

• Login card redesigned — glass border, background grid overlay, gradient glow
• Larger border radius across all elements (rounded-xl inputs, rounded-2xl cards)
• Increased form spacing (space-y-4 sm:space-y-5)
• Dimmer placeholders (text-gray-600/40)
• Loading splash screen with spinner and refresh hint
• Light mode sidebar tooltip

Data Integrity

• Fixed double-creation race conditions in habits, goals, and journal stores
• Client-side limits: max 10 habits, 20 tasks/day, 1 journal entry/day
• Analytics skips entries before habit createdAt date
• Profile dropdown uses bg-surface classes for proper light mode rendering

Migration

• Migrated to new Firebase project: atlscoup
• Old domain (atlcoup.web.app) now 301 redirects to atlscoup.web.app
• Updated CSP headers for hCaptcha and Google Fonts
• PWA manifest and service worker rebuilt from scratch

Pages

• Landing page redesign with hero, feature cards, pricing table, FAQ
• Privacy Policy, Terms of Service, 404, and Verify Email pages
• Settings panel with account management, password change, deletion
