/**
 * contact.css — Contact page specific styles
 * Premium navy header + bone-ramp split (info aside + white form card).
 * REUSES the global form.css kit verbatim (.form, .form-field, .form-input,
 * .form-textarea, .form-error, .form-honeypot, .form-privacy, .btn--full).
 * Page CSS only styles the page shell, header, split layout, info aside,
 * the form card wrapper and the status-container surfaces.
 * Depends on: tokens.css, layout.css, base.css, form.css, button.css
 * Copper TEXT on light surfaces uses --c-copper-text (AA 5.53:1); on dark
 * surfaces --c-copper / --c-copper-bright is used.
