/*
 * Look of the identity provider's sign-in pages (Login, Mfa, RecoveryCode, EnrolMfa), so they read as the same product
 * as payplus-web. Colours, fonts and radius are copied from payplus-web src/styles/tokens.css and the brand treatment
 * from its /auth pages (src/components/ui/plainPage.ts); change them there first, then here.
 *
 * Served as a same-origin static file because the pages' Content Security Policy allows stylesheets from 'self' only:
 * no inline styles, no web fonts, no CDN. Fonts are the system stacks payplus-web uses until its fonts are approved.
