 // Per RFC-WS-FRONTEND-PRIMEVUE AD-2: darkModeSelector matches Vuexy's
 // `.dark` class convention so existing skin-toggle plumbing continues
 // to work during the F3–F6 parallel-mode window.

+// Exported as a NAMED function (no `export default`) on purpose: the
+// Vuexy registerPlugins() helper (src/@core/utils/plugins.ts) globs
+// plugins/*/index.{ts,js} and invokes the `default` export of each
+// match. A default export here would cause PrimeVue + its three
+// services to register twice — once via registerPlugins, once via the
+// explicit installPrimeVue(app) call in main.ts. The named export
+// keeps the explicit installer in main.ts as the single registration
+// site, which is the design intent (decouple PrimeVue from the Vuexy
+// @core machine so F6 can delete @core/ without affecting PrimeVue).
