⭐ Key Features Added

1. 🏆 Multi-Platform Competitive Programming Integration

• Codeforces Integration: Render real-time Codeforces stats directly in your profile dashboard, showing current rating, current rank, and solved problem counts (via user status lookup).
• CodeChef Integration: Displays current rating, star ratings, global rank, and calculated division layout directly in a dedicated competitive programming section.
• Adaptive CP Cards Section: Automatically restructures and sizes platform cards based on which parameters are provided, preventing clutter and keeping layouts clean.

2. 🎨 Theme Exploration & Gallery UI

• Searchable & Filterable Theme Gallery: Filter themes by category chips and search by theme name with autocomplete suggestions.
• Clickable Theme Cards: Selecting themes from the gallery scrolls directly to the live preview and updates setup configs instantly.
• Theme Comparison Page: Compare different themes side-by-side on a dedicated comparison dashboard layout at /theme-comparison.html.
• Theme Preview Gallery: A visual preview showcase gallery displaying dashboard samples on the landing page.

🖌️ 3. Themes & Customizations

• 20+ New Dashboard Themes: Added Cobalt2, One Dark, GitHub Light, AI/ML, Android Studio, Ember Glow, Forest Night, Game Dev, Material, Midnight Neon, Monokai, Nord, Oceanic Next, One Dark Pro, Pastel Dream, Synthwave '84, Tokyo Night, Web Dev, Xcode, and more.
• Developer Persona Themes: Handcrafted profile themes tailored for specific engineering domains (e.g., AI/ML, Game Dev, Web Dev).
• Dynamic Custom Themes: Support for defining your own custom themes on-the-fly using query parameters directly in the URL.
• Light/Dark Mode: A modern toggle for switching the landing page between light and dark visual aesthetics.

🛠️ 4. Customization & Interactive Tools

• Trophy Customizability: Added the hide_trophies query parameter to allow hiding individual trophies in both the backend and frontend generator UI, as well as a new Pull Request reviews trophy.
• Reset Form Functionality: Added a dedicated button to instantly clear/reset user configuration inputs in the generator.
• Quick Start Copy Buttons: One-click copy buttons in the integration guide to copy Markdown snippets.
• Download PNG & SVG Buttons: Dedicated download buttons to save generated SVGs or convert and download them to PNG files.
• Semantic SVG Accessibility (A11y): Built-in screen reader support, descriptions, roles, and accessible labels for all generated dashboard SVGs.
• Graceful Failures with Error SVGs: Returns clean, styled Error SVG cards when external APIs fail rather than failing the request or returning empty pages.

📱 5. UI/UX & Responsive Layouts

• Responsive Mobile Navbar: Smooth hamburger menu for small screen devices.
• Mobile Optimizations: Cap avatar sizes, wrap code blocks with horizontal overflow, and remove hardcoded table widths to ensure the README generator is 100% responsive.
• Interactive Enhancements: Animated underline transitions on navbar links and smooth scroll-to-top buttons.
• Visual Indicators: Live loading spinner indicates preview generation states.

⚡ 6. Performance & Security Hardening

• Size-Limited LRU Cache: Replaced standard cache implementation with a strict LRU eviction cache to completely eliminate memory leak risks.
• Fetch Timeouts: Implemented a hard 8-second fetch timeout for Codeforces, CodeChef, GitHub, and LeetCode API requests to prevent server hang-ups.
• MongoDB Connection Breaker: Integrated a circuit breaker on MongoDB logger connection logic to prevent repeating 10s connection timeouts from blocking request execution.
• Content Security Policy (CSP): Fully implemented CSP headers and input hardening on endpoints.
• Query Validation & Normalization: Centralized input sanitization and strict validation regex rules to defend against injection and ReDoS vulnerabilities.
• Anonymization: Masks the last octet of user IP addresses before writing logs to MongoDB.

---

🧪 Developer Experience & Testing

• Unified Test Framework: Converted all existing tests to Jest, providing a unified test running suite (npm run check).
• API & SVG Render Unit Tests: Added coverage for external API service modules (GitHub, LeetCode, Codeforces, CodeChef) and SVG render templates.
• Visual Regression Snapshots: Integrated Jest visual regression snapshots to keep SVG structures consistent and prevent unintended visual layout shifts.
• Lightweight CI Check Pipeline: Configured linting, formatting check, unit tests, coverage, and issue auto-labelers as automated GitHub Actions.
