/**
 * Hides cartographic captions that overlap.

 * @description
 * At low zoom, permanent captions pile on top of each other and the map becomes
 * unreadable — every label unreadable rather than a few missing. The first
 * caption in DOM order wins each conflict and the rest are hidden, which is the
 * standard cartographic trade: fewer labels, all legible.
 *
 * Hidden captions are made `visibility: hidden` rather than unmounted, so the
 * decision reverses instantly when the user zooms back in, and nothing about
 * the accessibility tree changes (captions are `aria-hidden` regardless — the
 * marker's accessible name already carries the text).
