   HERO-REDESIGN.CSS — Vision Therapy Institute
   A balanced split hero: editorial copy (left) + a softly-blended,
   naturally-scaled clinic photograph (right) on a premium navy stage.
   On-brand blues (#1A6BDA / #5B9AFF / #8FB8FF) over deep navy (#07111F).
   Loaded LAST so it owns the hero — self-contained, no dependency on the
   old .hero / carousel styles. Scoped to .vh-hero.
