Technical Highlights

Accessibility (WCAG 2.1 AA)

// ARIA live regions for dynamic content
<div role="status" aria-live="polite" aria-label="Saving changes">

// Proper ARIA attributes
<button aria-label="Connection status: Live" aria-expanded={visible}>

// Screen reader support
<span className="sr-only">Current theme: {theme}</span>

// Keyboard navigation
useEffect(() => {
  const handleEscape = (e: KeyboardEvent) => {
    if (e.key === 'Escape') setVisible(false);
  };
}, []);

Animations & Transitions

// Smooth fade-in
className="animate-in fade-in duration-200"

// Scale effects
className="hover:scale-105 active:scale-95"

// Color transitions
className="transition-all duration-300"

// Pulse animation for urgency
className={isLowTime ? 'animate-pulse text-danger' : 'text-accent'}

Responsive Design

// Mobile-first typography
className="text-[10px] sm:text-xs"

// Responsive layouts
className="grid grid-cols-2 gap-2 sm:gap-3 md:flex md:gap-4"

// Touch targets
className="min-w-[28px] min-h-[28px]"

// Viewport-aware positioning
const rect = tooltip.getBoundingClientRect();
if (rect.top < 0) newPosition = 'bottom';

CSS Variables for Theming

// Consistent theming
className="text-(--muted) hover:text-(--accent)"
className="bg-(--surface) border-(--border-hi)"
style={{ backgroundColor: 'var(--success)' }}
