/**
 * Walters Construction FL — Hero Section Component
 *
 * Full-viewport hero with video background (drone footage), static image
 * fallback, and content overlay containing the brand logo, 20-year
 * anniversary badge, and call-to-action buttons.
 *
 * Depends on styles/variables.css for brand tokens.
 * Video is hidden and replaced by a static image on mobile (< 768px) to
 * conserve bandwidth; this is enforced via CSS display rules combined with
 * JS-conditional loading in hero-video.js.
