/* Cave — styling for the embedded Usher OIDC auth pages
 * (sign-in, two-factor, password reset, email verification).
 *
 * Usher renders these pages with stable usher-* class hooks; this sheet
 * themes them in "Terminal Warmth" using the variables defined in cave.css,
 * which is loaded ahead of this file. Keep this file dependent only on those
 * variables so the palette never drifts from the main app.
