/* ============================================================================
 * form.css — shared form-widget styling for the 3 owned forms (contatti,
 * farmacovigilanza, lavora-con-noi). Targets the BEM classes already on the
 * form markup (`.contact-form__input`, `__textarea`, `__consent`, `__submit`, …
 * — see src/pages/contatti.php) rather than re-deriving new class names, so the
 * same stylesheet styles all three forms' fields without per-page overrides.
 *
 * PROVENANCE: docs/design-baseline/contatti-body.demo.html's <form> inputs —
 * STYLING only (rounded-lg border-border bg-card px-4 py-3 text-[13px], focus
 * ring, primary submit button). The demo's own field set (Nome completo/
 * Oggetto) is wrong and NOT reproduced — our forms keep their real CF7 fields;
 * this file only restyles them. base.css must load before this file (tokens,
 * preflight); loads after content.css (form cards live inside content cards).
