   Neft Teacher — Background Color Picker (Shopping Mall Mogul project pages)
   Lets a student recolor the page (background, cards, panels) and the banner.
   Colors arrive as CSS variables set by bg-picker.js; nothing changes until a
   student picks something. Hidden on print. Reference as
   /shared/bg-picker/bg-picker.css
