/**
 * AgentForms — Frontend Form Styles
 *
 * Scoped to .agentforms-wrapper to avoid leaking into themes.
 * Supports light (default) and dark themes via data-af-theme attribute.
 *
 * Design principles:
 * - Neutral, professional styling that blends with most WordPress themes
 * - CSS custom properties for easy customization
 * - Responsive, mobile-first
 * - Accessible (focus states, contrast)
