Version 6.6 (WEB-VERSION-34)

🟢 Latest Release October 2, 2026
UI/UX Toast System Above-the-Fold PWA v34
UI
Approved Modern Navbar & Hero Trust Strip Redesign: Transformed the navigation header with a live ● 100% Offline status pulse badge, subtle link styling, and clean vector action pills (Android App, PC Toolkit). Elevated the hero section with a frosted cryptographic trust strip highlighting AES-256-GCM, 600,000 PBKDF2 Iterations, and 100% Air-Gapped architecture. Tightened shell vertical gaps (4rem → 2.25rem) and hero spacing, bringing encryption drop zones directly above the fold on all standard laptop displays.
New
Non-Blocking Toast Notification System: Replaced all blocking native window.alert() prompts with a sleek glassmorphic toast notification component (showToast) featuring auto-dismiss, smooth entry animations, and contextual state indicators (info, warning, error, success).
UI
Interactive Validation & Error Shake: Added animated inline field shake (@keyframes fieldShake) to drop zones and password inputs on validation errors, providing immediate visual feedback without halting JavaScript execution.
UI
Card Symmetry & CTA Baseline Alignment: Unified Encrypt and Decrypt card heights with CSS Grid stretch alignment and bottom-pinned primary action buttons via margin-top: auto, eliminating awkward vertical voids.
Fix
Streaming Mode Badge Stretched Width Fix: Resolved the 440px wide stretching bug in the Streaming Mode toggle container (.v2-badge) by enforcing align-self: flex-start.
Fix
Floating PWA Install Banner: Converted the full-width bottom PWA install banner into a discreet floating card docked to the bottom-right corner, backed by 7-day dismissal persistence in localStorage so it never blocks vault drop zones.
UI
Tablet (≤ 820px) Tab Switching Synchronization: Enabled dynamic single-panel tab switching across tablet viewports, eliminating double-card vertical stacking and excessive page scrolling.
PWA
Service Worker Cache Synchronization: Bumped Service Worker offline shell cache to v34 (WEB-VERSION-34).

Preserved root fallback for direct browser requests (/favicon.svg).
Fix
PWA Manifest & Dynamic Service Worker Aliasing: Synchronized PWA manifest.json icon routes and all relative HTML references. Added intelligent Service Worker fallback regex in sw.js that intercepts legacy root image requests and transparently serves them from assets/ cache without broken links.

UI Polish Mobile UX Contrast PWA v27
UI
Light Theme Nav-Pill & Password Field Contrast: Fixed low-contrast styling in light theme where navbar action buttons (.nav-pill) were washed out and password input fields (.field-input) rendered dark text on dark backgrounds; enforced crisp white input containers, dark slate text (#0f172a), high-contrast placeholder colors, high-impact CTA gradients, and refined drop-zone borders.
UI
Mobile Micro-Hero: Replaced the hidden mobile header with an elegant, space-efficient micro-hero displaying the privacy badge, responsive title, and two-line clamped tagline so mobile visitors retain immediate context and security reassurance.
UI
Glassmorphic Specular Card Elevation: Enhanced the primary encryption and decryption vault cards with top specular highlights (box-shadow: inset 0 1px 0 rgba(255, 255, 255, 0.12)), multi-layer backdrop blurs, and tuned hover glows.
