   SCALING STRATEGY:
   .hero-scale-wrapper is a CSS container with
   fixed aspect-ratio (950:620) and fluid width.
   It acts like an SVG viewBox — all children use
   position:absolute with % coordinates, and font
   sizes use cqi (container query inline) units.
   Everything scales proportionally with ZERO JS.
