/**
 * v1.4.27 MB6 — `/measurements?add=<TYPE>` consumer.
 *
 * Insight metric actions link here with `?add=<TYPE>` and an optional,
 * allowlisted `returnTo`. The page opens the responsive capture primitive,
 * pre-selects the matching type, and strips the query without losing the
 * one-shot return context.
 *
 * The browser contract covers the populated-page action, legacy preselection,
 * failure retention, success return, and rejection of an external destination.
 * Playwright runs every case in both the desktop Chromium and Pixel 5 projects.
