Responsive Layout Patterns
Stack to Grid
// Mobile: stacked, Desktop: side-by-side
<div className="flex flex-col lg:flex-row gap-8">
<div className="lg:w-2/3">{mainContent}</div>
<aside className="lg:w-1/3">{sidebar}</aside>
</div>
Hide/Show by Breakpoint
// Mobile menu vs desktop nav
<nav className="hidden md:flex">{desktopNav}</nav>
<Sheet className="md:hidden">{mobileNav}</Sheet>
Responsive Grid Columns
<div className="grid grid-cols-1 sm:grid-cols-2 lg:grid-cols-3 xl:grid-cols-4 gap-6">

Key Principles
- Consistent Structure — Same page types should follow same patterns
- Content Hierarchy — Most important content first, above the fold
- Progressive Disclosure — Don't overwhelm; reveal complexity as needed
- Mobile-First Flow — Design the mobile layout first, then enhance
- Reusable Compositions — Build page templates from component patterns
