/**
 * Superable Course Player Engine — layout stylesheet.
 *
 * Generic course-player chrome (sidebar nav, module list, content area, nav
 * buttons). Consumes tenant branding as CSS custom properties set elsewhere
 * (--color-primary, --color-bg-light, --color-text-dark, etc.) rather than
 * hardcoding any tenant-specific values here — that's the interface boundary
 * between this file and the platform's tenant branding CSS.
 *
 * Extracted unchanged from player.php's former inline <style> block.
