/* =====================================================================
   Real experience (Views/Shared/_RealExperience.cshtml): /bootcamp hero, /courses, bootcamp detail page
   A glass "app window" that plays a short storyboard over real screens of the learning app: a camera moves into the part
   that matters while a few lines are typed, then the next tab starts. Same language as the home hero (home-hero.css).
   .rx--hero = compact, stage only. Phones: the same camera zooms into the readable area and the narration sits under the window.
   Radii: 12 (controls) / 18 (window) / pill. All motion is off under prefers-reduced-motion.
