/* =========================================================================
     Customer Portal — redesigned May 2026 to match the staff studio shell.
     Navy sidebar (deep lift on the customer-blue), warm cream canvas, Inter,
     white cards. Restyles the existing markup + JS-emitted classes in place
     so all data-loading + modals keep working unchanged.
