/* styles/login.css
 *
 * Styling for the login overlay only. Every selector is prefixed `ui-` and
 * scoped under #fpbx-login-root, so nothing here can reach the phone UI.
 *
 * phone.css is treated as protected in this project (README, "Notes") — it is
 * not touched. These rules replace the inline styles the overlay used to carry
 * in index.html.
 *
 * The tokens below reproduce the previous overlay's palette exactly, so the
 * migration is visually identical.
