Overview

This PR merges the dev branch into main, delivering comprehensive platform features, interactive DSA visualizer enhancements, system design simulation labs, community hub, and brand design polish.

Key Highlights

1. Interactive Data Structure Visualizer:

   • Polished visual representations across all structures: Linked Lists (Singly, Doubly, Circular with return tracks), Binary Search Trees, Complete Binary Heaps, and Graph Networks.
   • Fixed coordinate bounds in spacious SVG viewports so no elements are cut off or covered upon insertion.
   • Complete algorithmic simulations and multi-language code snippets across TS, JS, Python, Java, C++, and Go for all operations (including BST Pre-Order/Delete, Heap Heapify/Peek, Queue Peek, Map Rehash, and Graph Dijkstra/Add Vertex/Add Edge).
   • Clean, concise array and linked list index addressing with comfortable spacing.

2. System Design & Studio Architecture:

   • Interactive Architecture Whiteboard canvas with smart edge connectors, topology analysis, and scenario labs.
   • Fullscreen Studio mode with collapsible docks.

3. Community Hub:

   • Community hub with verified solutions, discussion threads, and clean leaderboard.

4. Brand & Design System:

   • Dynamic theme-aware SVG logos on auth pages (/sign-in, /sign-up), replacing raster screenshot PNGs with crisp vector wordmarks for both light and dark modes.
   • Comprehensive SEO suite with dynamic OpenGraph images, Twitter cards, sitemap, and robots configuration.
   • Accessibility audit compliance and mobile-responsive layout verification.

Verification

• Vitest: 91/91 test suites passing (1,321/1,321 tests).
• TypeScript & ESLint: 0 errors, 0 warnings.
