+/* "Dependency required" card — e.g. "Enable Whitelist — Traefik needs
+   to be installed" on the Features tab. Two-row grid so the action
+   button always lives in its own full-width footer row, regardless of
+   how narrow the card column is. The old single-row flex layout broke
+   in 3-column grids: the body squashed into a 30-char column and the
+   button stretched vertically as the only flex item with breathing
+   room. Grid keeps icon + body on one row and the button on the next,
+   so the visual reads top-to-bottom: who is this for → what's missing
+   → fix it. */
