/**
 * Lafoura Auth — login form.
 *
 * Faithful to the Lafoura Login artboard: a single 420px card sitting near
 * the top of an empty field, square corners, hairline borders, one near-black
 * accent, and Vazirmatn served from the plugin so the page never waits on a
 * font CDN.
 *
 * Every component rule is scoped under .lf-auth. Themes routinely style
 * `input[type="tel"]`, which outweighs a lone class, and this form has to
 * render at the artboard's exact metrics inside whatever theme is running.
