/**
 * WP-Porto-Sender — front-end request form.
 *
 * Base styling plus three preset layouts (stacked / compact / card). Colours and
 * spacing are driven by CSS custom properties that RequestForm::render() sets in a
 * small scoped inline <style> from the plugin settings:
 *   --porto-accent, --porto-btn-bg, --porto-btn-text, --porto-max-width, --porto-gap
 * The declarations below double as fallbacks if that inline style is ever absent.
