/*
 * auth.css — styles for auth controls, modal, user menu, dashboard, and
 * saved-teams cards. Worktree C owns this file.
 *
 * Theming:
 *   Reuses the CSS custom properties defined in `assets/style.css`
 *   (`--background-color`, `--text-color`, `--card-background`,
 *   `--accent-color`, `--shadow`, `--shadow-inset`, `--highlight`).
 *   Both light and dark themes are inherited automatically because
 *   `body.dark-mode` flips the same vars.
 *
 * Mobile-first:
 *   Defaults are tuned for ≥320px width. Wider breakpoints upgrade the
 *   dashboard from a single column to a multi-column grid.
