v4.0.0 - Stack Modernization, SSR Syntax Highlighting, and AI Agent Discovery Protocols

This major release represents a complete modernization of the website architecture, migrating from legacy build tools to a modern Vite pipeline, introducing Server-Side Rendering (SSR) for syntax highlighting to optimize Core Web Vitals, and implementing standard protocols for AI Agent Discovery and Authentication.

Key Highlights

Infrastructure & Build System Modernization

• Vite Migration: Replaced the legacy Grunt-based pipeline with Vite and Vituum for fast builds and hot module reloading.
• CI/CD Upgrades: Modernized GitHub Actions workflows to use actions/checkout and actions/setup-node v6 compatible with Node 24.
• Dependency Updates: Upgraded all packages to their latest versions and pruned obsolete vendor dependencies (e.g. jQuery, PostCSS).

Performance & Core Web Vitals (LCP & INP)

• SSR Syntax Highlighting: Migrated code syntax highlighting to build time using server-side PrismJS compilation, removing client-side prism.min.js to eliminate runtime parsing and rendering blocks.
• Critical CSS Inlining: Implemented a custom Vite plugin (inline-css-plugin) to inline critical styles directly into the pre-rendered HTML, removing render-blocking CSS tags.
• Asset Optimization: Migrated all portfolio and static assets to highly compressed WebP format.
• Font Loading: Refactored Google Fonts imports to target specific weights and implemented asynchronous font loading.

Accessibility (a11y) & SEO Enhancements

• A11y Refactoring: Normalised the console template structure and flattened navigation links to ensure screen-reader friendliness.
• Footer Improvements: Added automated copyright year generation and simplified boilerplate copyright declarations.
• SEO Cleanups: Standardised header hierarchy (ensuring exactly one <h1> per page) and improved OpenGraph/Twitter social meta-tags.

AI Agent Discovery & WebMCP Integration

• Discovery Protocols: Implemented standard .well-known endpoints for AI client negotiation:
  • /.well-known/oauth-authorization-server
  • /.well-known/oauth-protected-resource
  • /.well-known/openid-configuration
  • /.well-known/jwks.json
  • /.well-known/api-catalog
• WebMCP Support: Integrated WebMCP communication (webmcp.js) and registered a WebMCP server card under /.well-known/mcp/server-card.json.
• Agent Capabilities: Added structured registration protocols (auth.md) and a skill catalog under /.well-known/agent-skills/ to describe developer portfolio details programmatically.
