/* De mezclas a atmósferas · course page v2 (insound.io/mariano-course-proposal).
   Layout: no columns, no side panel. Each lesson is one full-width page: the stage (where Mariano's video plays)
   runs edge to edge, the lesson flows under it at a gutter that grows with the screen, and the next lesson
   closes the page as a full-width band. The index is a full-screen overlay. Instruments are fixed-size objects
   with their controls drawn inside them. Everything is scoped under .mxa; the page is a fixed layer over the storefront. */
