/* Education app development (/education/app-development). Every class is prefixed edapp.
   The tablet and phone are HTML/CSS illustrations of a made-up centre, "Your Academy". Their screens stay
   light in both themes, like screenshots, and are sized in --u: one design pixel of the device screen
   (tablet screens are drawn at 440 wide, phone screens at 170), so each device scales as one piece.
   Motion (transform and opacity only) runs with html.motion; src/js/edu-app.js drives the day story
   and the planner. Without JS or with reduced motion everything stays readable and still. */
