/* =============================================================================
   ExamON - PER-SCREEN STYLES
   -----------------------------------------------------------------------------
   Screen-specific blocks only. The shared layer - design tokens, top chrome,
   page shell, and every reusable component (buttons, cards, tables, forms,
   badges, empty states, overlays) - lives in assets/css/examon_ui.css, which
   loads BEFORE this file.

   RULE: never redefine a component that examon_ui.css owns. Because this file
   loads second, any such rule silently wins and the shared restyle stops
   working. That is exactly what had happened before 2026-08-11: .btn was
   declared twice (line 296 and line 3199) and the tail copy won app-wide.

   Removed 2026-08-11 during the Apple-Glass re-skin:
     - lines 1-1062   the old core (tokens, nav, page shell, and every
                      component) - now owned by examon_ui.css
     - lines 1384-1489, 1679-1877, and a third copy in the Setup and Marks
                      Entry section: three verbatim duplicates of the form-v2
                      block, one also carrying a second csel engine
     - btn-setup-marks x2 (2357, 2628) - unified as .btn-act in examon_ui.css
     - btn / btn-sec / btn-sv (3199-3203) - now in examon_ui.css
   Also dropped as provably unreferenced (no view, controller or JS used them):
     sect-banner, step-hdr, setup-list/setup-row/sr-, s-sel, msel-,
     term-list-wrap/term-box, ch-opt, custom-tog-color
   (s-label WAS in use across 24 sites and now lives in examon_ui.css section 8.)
