/**
 * Intervia Leads Form — frontend styles.
 *
 * Aligned with the Intervia design system (docs/GUIA-ESTILOS-INTERVIA.md):
 * straight corners, underline-only inputs, mono tracked labels, gold action
 * buttons with arrow, mono progress with a gold rule.
 *
 * Tokens reference the site's global variables (var(--gold, …)) with a brand
 * fallback, so when the plugin runs inside interviags.com it inherits the live
 * theme — including [data-theme='dark'] — and still looks correct standalone.
