+    <!-- ★ THE SELECTIONS ROW IS PERMANENT — it must never leave the DOM.
+         This was v-if="useFilters && chips.length", so the row DISAPPEARED whenever nothing was
+         selected. That is the actual bug, and it is layout shift rather than chip placement:
+           "whenever I deselect it, it removes that space from the second header... the decompression
+            of the height causes the ENTIRE LOWER APP TO SHIFT UPWARD, which makes it really hard to
+            track with your eyes." (Driver, 2026-09-22)
+         A row that appears on select and vanishes on clear moves the map, the table and the grid on
+         every single click. The row now always renders and only its CONTENTS change, so nothing below
+         it can move.
+         The empty state is "World" — the Driver's word, and it reads correctly too: no filter really
+         does mean the whole world is in scope. Clear-all is omitted rather than the row collapsing,
+         because there is nothing to clear; the row keeps its height either way. -->
