+# 5x sweep 3
+Result: 3x 7/7, but extended 8s real-Chrome capture caught a console 404 with NO >=400 response captured.
+CAUGHT: /favicon.ico 404 — page declared no favicon, so the browser auto-requested /favicon.ico (browser-level, outside the page-response events), which 404'd. Intermittent vs 3x because the favicon fetch lands after M3's short window.
+FIX: added an inline data-URI SVG favicon (gauge motif) to <head> so the browser never requests /favicon.ico.
