/* ── Universal Sticky Navigation Footer ── */
/*
 * Layout: 3-column CSS Grid.
 *   Column 1 (1fr) — Back button, pinned to the left rail.
 *   Column 2 (auto) — Contact info, self-centered.
 *   Column 3 (1fr) — Next button, pinned to the LEFT EDGE of its column.
 *
 * Because columns 1 and 3 are equal 1fr fractions, the left edge of column 3
 * is always at (footer_inner_width + contact_width) / 2 — a value that depends
 * only on viewport width, never on the button's own text length.
 * justify-content: space-between is intentionally removed: it was the cause of
 * the right button drifting left whenever the label text grew longer.
