/**
 * Standalone post-signup welcome modal chrome (BEM).
 *
 * Self-contained — does NOT depend on login-overlay.css — so the welcome +
 * newsletter modal survives the SSO cutover that removes the login overlay.
 * Visual treatment intentionally mirrors the login overlay. The newsletter
 * opt-in styling lives in welcome-newsletter.css (scoped under .welcome-block).
 * See docs/04-Architecture/kodansha-auth-sso-integration.md §W1.
