/* fpmAuth.css — public auth pages (invite accept / set password).
 *
 * The customer's FIRST impression of IronLink, so it must read as the product:
 * deep-navy console, teal accent, Inter. Styles the markup in
 * IronLink/public/invite.html and drives the JS state classes in
 * IronLink/js/invite.js (fpm-auth-hidden, fpm-auth-met/unmet, fpm-auth-shown).
 * Tokens only — no raw hex/rgba — so it tracks the same light/dark theme as the
 * rest of the console.
 *
 * Catalog: CONSOLE.md → "Auth (public invite / set-password page)".
