+<!--
+  MapControlMenu.vue — the ONE menu every map control opens.
+
+  A control (share, export, …) only toggles `open`; this component owns where the menu
+  lives and how it behaves, on phones and desktop alike:
+
+    • It renders INSIDE the map area (teleported out of the toolbar into the same shadow
+      root), so it never escapes the map's walls, never uses position:fixed, and scrolls
+      with the map when the host page scrolls.
+    • Its top edge is the toolbar's top edge and its max height is the toolbar column's
+      height — every menu of a map shares the same band, whichever button opened it.
+    • It opens on the toolbar's inner side: to the LEFT of right-hand controls, to the
+      RIGHT of left-hand controls. The side is measured, so a right-to-left page that
+      mirrors the toolbar mirrors the menu as well.
+    • Width: as wide as fits between the toolbar and the opposite edge, capped at `width`.
+    • One z tier for menus (--z-menu, default 3000); only one menu is open per map at a
+      time; closes on Escape or on a tap on the bare map canvas (never on legend/search).
+
+  Props: open (Boolean), title (String), isDark (Boolean),
+         width     (Number, 340)  — preferred width; shrinks to what fits (mobile friendly)
+         maxHeight (Number|null)   — cap below the toolbar column's height (null = the column)
+         height    (Number|null)   — a fixed height instead of fitting the content
+  Emits: close
+  Slot:  the menu content (tabs, buttons, text) — chrome (header, close) is provided here.
