/* client/css/auth.css
 * Standalone auth pages (login, signup, waitlist).
 *
 * Visual language inspired by monarch.com's auth flow:
 *   • Centered narrow card on a warm/ivory background
 *   • Logo + brand mark above the card, never inside it
 *   • Generous whitespace, soft 1px borders, large rounded inputs
 *   • Primary CTA fills the card width
 *   • Optional right-rail "testimonial" panel on signup
 *
 * Self-contained — no dependency on styles.css. v2.css is still
 * linked for shared favicon/meta consistency.
