   Course Price Manager — per-app styles  (apps/course-price-manager/app.css)
   --------------------------------------------------------------------------
   Loaded AFTER shared/theme.css. Two jobs:
     1. Set this app's accent palette (here: Apexis green — the default brand).
     2. Define the bespoke components this app needs that aren't in the shared
        design system (course cards, planner panels, promo/group/partnership UI).
   Generic pieces (header, tabs, inputs, buttons, modal, toggle, toolbar, cards,
   stat-card, grid helpers, badges, status) all come from theme.css.
