/**
 * Flash Landing Page – Main Styles
 * =================================
 * REWRITTEN: Rebuilt from the ground up to match the new page
 * structure. Key changes:
 *   - Removed metrics, download, newsletter, video-demo sections
 *   - Added: why-flash, how-it-works, status, founder sections
 *   - Consistent CSS variable system with dark mode support
 *   - System font stack (no external dependency fallback)
 *   - Screenshot placeholder styles for hero visual
 *   - Account deletion styles (required for Play Store compliance)
