   Modaam Auth — shared styles for login / otp / otp-verify / register

   NOTE: selectors below are prefixed with `#auth` on purpose. The legacy
   `style.css` has old id-based rules (`#auth input[type=...] { border:0 }`,
   `#hero, #auth { background:url(hero-bg.jpg) }`, `#auth a { font-size:14px }`,
   `#auth button { ... }`) that otherwise win by specificity even though this
   file loads after it.
