/* ApexOS / RoofOps — SPA system styles
 * Extracted from the inline <style> block previously embedded in
 * public/app.html so the SPA shell, pages, badges, buttons, forms,
 * modals, calendar, photos, tabs, and SMS hub pick up a single
 * shared stylesheet that consolidates the design-system tokens and
 * component classes used by app.html.
 *
 * Token palette: theme.css owns the brand defaults (RoofOps amber +
 * navy). System.css adds the SPA-only purple/green/yellow/red status
 * set used by the production-management and CRM UI inside public/app.html.
 * Where theme.css also defines the same class (e.g. .btn, .input,
 * .modal) the SPA must keep its variant — those classes were tuned
 * for the production module and removing them would regress the
 * existing visual behavior of /app/*.
