/* ==========================================================================
   MySchoolOS Entry PWA — shared design tokens
   Brand colors are pulled straight from the tenant login screen
   (tenant_Ci4/app/Views/backend/login.php: --brand-950 #161950,
   --brand-500 #465fff) so the app, the landing page and the tenant portal
   read as one product. Pink is this app's own accent, layered on top for
   the "flow" landing treatment — the offline page deliberately stays
   pink-free and closer to the tenant screen's own navy/blue look.
   No external fonts/CDNs anywhere in this file — every page here (this
   one especially, once cached) has to render correctly with zero network.
