/*
   Avlory app UI layer: account/app pages (dashboard, login, client portal, checkout, admin, employee).
   Toasts, confirm dialogs, skeleton rows and fallbacks for the shared components.

   Load order on app pages: css/tokens.css -> style.css -> css/app-ui.css -> css/components.css -> page css.
   Contract tokens (--danger, --surface-1, ...) live in tokens.css; this file never defines them, it only
   reads them with fallbacks, so the pages look right before tokens.css/components.css exist.
   The fallback .btn/.skip-link/.field-error rules below sit before components.css, which wins when present.
