/*
 * style_masterpiece.css
 *
 * A modern, elegant redesign of the original meditec landing page.
 * This stylesheet defines a comprehensive layout with responsive
 * navigation, parallax hero header, feature cards with optional
 * details, a scroll-snap carousel for product categories, a contact
 * form with select dropdowns and a polished footer. The colour
 * palette preserves the original blue tone while introducing a
 * complementary accent colour. Care has been taken to ensure
 * graceful degradation on older browsers and accessibility for
 * assistive technologies.
