/* =============================================================================
 * ALL STEEL - FOOTER
 * -----------------------------------------------------------------------------
 * Five-column layout. No brand/logo block.
 * Column 5 contains a branded social list (icon + name per platform).
 *
 * Key fixes from previous version:
 *   - Hover state no longer adds border + padding (caused layout jump).
 *     Uses a left-indent colour shift instead - smooth, no reflow.
 *   - .footer-nav h4 now covers all five columns via a single selector.
 *   - .social-list items styled with per-platform brand colours.
