+/**
+ * Live Tracking — Property Detail Drawer (issue #251)
+ *
+ * Verifies the row-click flow on the Measures tab: clicking a row in the
+ * MeasuresTable opens the PropertyDetailDrawer and all six stage-ordered
+ * sections are visible in the body.
+ *
+ * The spec assumes an authenticated session can be reused (or skipped) the
+ * same way the rest of the suite handles it. Because live tracking is a
+ * portfolio-scoped page, the test reads the target portfolio slug from the
+ * `LIVE_PORTFOLIO_SLUG` Cypress env var so it can run against any seeded
+ * environment without hard-coding an ID.
