/* All AI v2 "Business Notebook": shared design system for Log in, Sign up, Plans, Checkout, /audit, 404 pages.
   Warm paper, ink floating header pill, white cards with a hairline rule, Instrument Serif headings, ONE blue (#2563FF) for buttons.
   NO green, NO yellow, no gradients, no glow, no photo backdrop. CSP-safe: no inline styles/scripts, same-origin assets only.
   Served at /auth-assets/auth-v2.css. Loaded after /static/fonts.css and /static/buttons.css, before auth-brand.css / audit.css / checkout-extra.css.
