+### Step 523: Sprint 26 Integration + Summary
+**Status:** PASS (8/8 tests)
+
+Implements the Sprint 26 closure gate by integrating Phase 26a reliability,
+visual token + identity systems, control/typography harmonization,
+modifier-edge shortcuts, overlay hardening, notification semantics, and
+cross-panel consistency into a single summary signal.
