/*
 * Meta navigation links — internal (dk-link-meta) and external
 * (dk-link-meta-extern, extern icon + "opens in new tab"). Used in the
 * footer's Rechtliches/Social rows (SD-120 revision: underline and 44px
 * touch target were missing — the `-line` span existed in markup but had
 * no styling, and the anchors stayed `display: inline` so `min-height`
 * from footer.css had no effect).
 *
 * Structure:
 *   .dk-link.dk-link-meta
 *     .dk-link-meta-label
 *       .dk-link-meta-text
 *       .dk-link-meta-line (underline bar, 1px default / 2px hover-active)
 *   .dk-link.dk-link-meta-extern
 *     .dk-link-meta-extern-icon (svg arrow)
 *     .dk-link-meta-extern-label
 *       .dk-link-meta-extern-text
 *       .dk-link-meta-extern-line
