/* auth.css — the auth surfaces (login + register) as one self-contained file.
 *
 * SCOPE: everything inside `.login-page` only. The My Songs / Albums overlays
 * (.cloud-modal*, .cloud-search) stay in styles/components/gallery.css untouched; the six `.cloud-*`
 * classes that WERE login-only (cloud-google-btn, cloud-divider, cloud-field,
 * cloud-email-form, cloud-auth-error, cloud-auth-actions) now live here,
 * scoped under .login-page so they can never leak into the app chrome.
 *
 * TOKEN CONTRACT (for the later app-wide phases): the --auth-* tokens below
 * are the first draft of the refreshed design system — warm cream canvas,
 * deep-green brand moment, lime as a spark (never a surface), borderless-
 * until-focus inputs, larger radii, one layered card shadow. Later phases
 * can lift these into the app-wide :root without renaming.
 *
 * PRINT: auth pages are screen-only. The print-hide rule for .login-page
 * lives in styles/base/print.css (@media print). This file defines no print rules and no
 * --print-* tokens (print geometry is PROTECTED — see styles/base/print.css and styles/score/preview.css).
 *
 * FONTS: "Sora" is the display voice (headings, primary buttons), Inter the
 * body voice. Both self-hosted via styles/base/fonts.css.
 *
 * Version token: this stylesheet is referenced as styles/pages/auth.css?v=r31-87808f4
 * in index.html and precached by sw.js; the deploy stamps it in one pass.
