[Feature Request] Add Feature Grid with Hover Reveal Section Component

[KeenIsHere]

📋 Component Proposal: Feature Grid with Hover Reveal

What is this component?

A responsive SaaS-style feature grid section with premium hover
interactions. Commonly used in modern landing pages to showcase
product capabilities in a visually engaging way.

🎯 Motivation

Many SaaS landing pages need a clean, reusable feature section
that demonstrates Animata's motion quality. Currently Animata
does not have a dedicated feature grid section component with
hover reveal interactions. This component would fill that gap
and serve as a strong Pro section demo.

📐 Proposed Layout

• 3 columns on desktop
• 2 columns on tablet
• 1 column on mobile
• Optional section title + subtitle header above the grid

🃏 Card Structure

Each card contains:

• Icon (accepts ReactNode)
• Title
• Short description

✨ Interactions

• Hover lift: translateY(-6px) smooth transition
• Border highlight: subtle gradient ring on hover
• Icon micro-interaction: scale(1.15) on hover
• All animations use transform and opacity only (GPU composited)

♿ Accessibility

• prefers-reduced-motion fully respected
• Semantic HTML markup
• Keyboard focusable cards
• Minimum 44x44px touch targets

🌗 Theme Support

• Full dark mode + light mode
• Tailwind design tokens only (no hardcoded colors)

📦 Props API

interface FeatureItem {
  icon: React.ReactNode;
  title: string;
  description: string;
}

interface FeatureGridProps {
  features?: FeatureItem[];
  columns?: 2 | 3;
  title?: string;
  subtitle?: string;
}

✅ Definition of Done

• Responsive across all breakpoints
• Smooth hover interactions (transform + opacity only)
• Dark and light mode tested
• prefers-reduced-motion handled
• TypeScript typed
• Stories file included
• Docs MDX written
• Preview screenshot ready
• Zero props renders useful default
