/**
 * plugin-designs/doxa-simple-map/index.js
 *
 * Bundle entry — registers the doxa-simple-map web component.
 *
 * ★ ITS TAG IS <dxm-simple-map>, DX Maps' own name. A host page can define the older generic names first
 * (DX Life's own /js/doxa-simple-map.js defines <doxa-map> and <doxa-simple-map>), and the first definition
 * wins, so under those names a page could be drawing the host's element instead of this one. The older names
 * are defined only when the host asks: a `data-legacy-tags` attribute on this bundle's <script>, or
 * window.DXM_LEGACY_TAGS = true before it loads. Each name gets its own class (one class under two tags is
 * undefined behaviour).
 *
 * Usage:
 *   <script src="<tree>/doxa-simple-map/doxa-simple-map.js"></script>
 *   <dxm-simple-map profile-config='{"profile":"doxa-simple-map","tk":"pk.eyJ..."}'></dxm-simple-map>
 * An existing embed that still writes <doxa-map> or <doxa-simple-map> adds `data-legacy-tags` to its <script>.
 *
 * The profile-config attribute is parsed by ProfileLoader (in @map).
 * `profile` must match a .vue file in this bundle's folder.
 *
 * Profile registry — Q3 contract from the migration plan: ProfileLoader lives
 * inside @map, so it cannot use import.meta.glob to reach into a
 * bundle's folder. The bundle MUST evaluate import.meta.glob('./*.vue')
 * locally and hand the result to the loader via app.provide('profileModules').
 *
 * Mapbox RTL text plugin: registered ONCE at module init (before any map
 * constructs), lazy-loads when Arabic/Hebrew text appears on the basemap.
