/**
 * listing-form.css
 * Business Listing Submission Form — Frontend Styles
 *
 * Design: Refined editorial — deep navy anchors, warm off-white surface,
 * Playfair Display for headings, clean structured form inputs.
 * Optimised for Core Web Vitals: no @import web fonts (use <link> in header),
 * no layout shift triggers, minimal repaints on interaction.
 *
 * Responsive: Single-column on mobile, two-column row on ≥600px.
 * ============================================================
