/* =====================================================================
   Calyxis — Responsive Hero
   Inspired by "Hero appearance - CSS Only" (codepen.io/bvg-studio/pen/vYjoxEK)
   Techniques retained: stacked CSS-grid layers, ken-burns zoom, clip-path
   reveal, staggered fade-in, color-overlay via ::before.
   Improvements: fluid clamp() sizing, svh units, no horizontal overflow,
   media-query fine-tuning, reduced-motion support, focus a11y.
