 * Lets wheel events reach the map natively when a zoom gesture started on the
 * map and the cursor later moves over the panel overlay.
 *
 * Pass-through uses `data-wheel-pass-through` + CSS `pointer-events: none` so
 * the browser delivers trusted wheel events to the map underneath. It is armed
 * only while a map-originated wheel gesture is in progress — panel-initiated
 * wheels and all pointer interaction keep the panel fully interactive.
 *
 * Gesture ownership is decided on the first wheel tick of each burst (after an
 * idle gap): target inside the panel shell → panel; otherwise → map. A
 * `pointerdown` on the panel ends any map wheel gesture immediately so clicks
 * and drags on the panel always win.
