 *                  Navigate list, Matters We Handle list, two foot-bottom
 *                  bars).
 *   - "minimal"  — About only: a single centered line, no practice links.
 *   - "standard" — the six practice pages and Contact: the same centered
 *                  line as "minimal", plus a .foot-links row (the six
 *                  practice areas; Contact's row additionally includes
 *                  About).
 * This is a confirmed correction to dockument, not an invention — see
 * this phase's completion summary. template-parts/footer/site-footer.php
 * implements all three.
