-		The flow canvas's controls — step palette, Save, Run, run history.
+		The flow canvas's controls are NOT listed here. They are declared on the
+		manifest page as `sidebarComponent: FlowDetailSidebar`, and #3103 made
+		CnAppRoot hand that component to this app through the #sidebar slot
+		prop, so App.vue renders it directly.
 
-		These are declared on the manifest page as `sidebarComponent:
-		FlowDetailSidebar`, and CnAppRoot does resolve that key. It could never
-		render here, though: CnAppRoot only falls back to it as the DEFAULT
-		content of its #sidebar slot, and this app fills that slot itself, so
-		consumer content wins by Vue's ordinary slot mechanic. The manifest key
-		was live config that rendered nothing.
+		A hardcoded <FlowDetailSidebar> used to sit here as a workaround from
+		when the manifest key rendered nothing. Once #3103 made the manifest
+		route work, BOTH rendered, and the e2e caught it exactly as it should:
 
-		The symptom was a flow page with no way to save, run, or add a step —
-		while its own empty state said "Add a step from the sidebar".
+		  strict mode violation: locator('.cn-flow-sidebar') resolved to 2 elements
+
+		The manifest is the single source of truth for a page's sidebar. Adding
+		a route here for a page that declares `sidebarComponent` will duplicate
+		it again.
