New Sidebar Navigation and Improved Search

We've added a persistent sidebar to the site that shows the full navigation structure at a glance. You can now quickly jump between Rankings, Prices, Compare, Learn, Market Reports, and News without hunting through menus.

What's New

• Sidebar navigation on every page showing all major sections with active state highlighting
• Bigger, centered search bar in the header with keyboard shortcut (Cmd+K / Ctrl+K)
• Simplified header focused on branding and search
• Mobile support with a hamburger menu toggle for the sidebar on smaller screens

AI/ML Content Reorganized

All AI and machine learning content has been consolidated under /gpu/learn/ai, including FAQ articles, use-case guides, and model pages. Old /ml/learn/* URLs automatically redirect to the new locations, so existing bookmarks and links will continue to work.
