/*
 * nr-footer — modern infrastructure-aesthetic footer.
 *
 * Layered on top of the inline footer styles in footer.php (which we
 * intentionally leave alone to avoid breaking the markup contract).
 * This file:
 *   - Replaces the bright blue/green Service & Support gradient with a
 *     dark navy + green-radial that matches the hero treatment
 *   - Mono-types the phone number, ASN, and copyright lines
 *   - Tightens column typography (smaller, tighter, more cards-of-info)
 *   - Adds an "infra status footer" row at the very bottom: ASN, IPv6
 *     readiness, BGP looking glass, status link — terminal-style
 *   - Monochrome social icons, square (not circular)
 *   - Subtler dividers, refined hover states
 *
 * Loads on every page via the always-on stack in functions.php.
