/**
 * PitaraAI - Global Stylesheet
 * =======================================
 * Layout, components, and animations for home and collection pages.
 * Uses CSS variables for design tokens; supports light/dark card states.
 * 
 * Structure:
 * - Global base styles and CSS variables
 * - Home page components (collections grid, hero input)
 * - Collection page: header, stats, cards grid, and expanded modals
 * - Card styles: collapsed state (icon + label) and expanded overlays
 * - Code editor modal and media viewer modal
 * - Hover animations and transitions
