   PRAGNA — Calm Glass Academy. Application layer on top of the Modernist
   system (styles.css). Loads AFTER styles.css. Two jobs only:
     1. A dark band, derived by inverting Modernist's own tonal ramps, so
        every component class (.btn .card .tag .table .input) works unchanged.
     2. The student experience: floating nav, editorial hero, cinematic
        course/lesson artwork. All names are prefixed pragna-* or reuse
        existing component classes — nothing collides with admin.css, which
        never loads this file.
