/*
 * Login page styles. Extracted from the inline <style> that used to live in templates/login.html:
 * kept there the pre-form HTML was ~13.6 KB (this CSS plus two inline brand SVGs), past Tomcat's
 * 8 KB response buffer, so the response committed before Thymeleaf reached the CSRF <form> — and a
 * render with no pre-existing session then threw "Cannot create a session after the response has
 * been committed". Serving the CSS (and the SVGs) as external static assets under /css/** (permit-all
 * in DefaultSecurityConfig) shrinks the pre-form HTML to well under the buffer, so the deferred CSRF
 * token is materialised before commit in every case.
 *
 * Copied verbatim from the SPA's register page (customer-portal-ui src/styles/register.css) so this
 * server-rendered login matches it one-to-one.
