+
+    Wraps every /my/* page (FP custom + Odoo default) in the new
+    sidebar shell. Inherits portal.portal_layout so we don't have
+    to edit every individual page template.
+
+    Implementation note (Approach D, $0 re-emit):
+
+    The plan originally proposed injecting an unbalanced main opening
+    tag in one xpath block and its closing tag in another. QWeb parses
+    each xpath payload as an independent XML fragment, so unbalanced
+    tags are rejected at load time.
+
+    Instead we use position="replace" on //div[@id='wrap'] with $0
+    inside the replacement payload. $0 is supported by Odoo 19's
+    Python view inheritance engine (tools/template_inheritance.py,
+    lines 162-169): any element whose text content is the literal
+    string "$0" has its text cleared and the deep-copied original node
+    appended as a child. This produces a fully balanced replacement tree
+    that nests the original #wrap (and all its Odoo-managed content)
+    inside our .o_fp_portal_main element.
+
+    Verified from portal_templates.xml line 155:
+        div id="wrap" class="o_portal_wrap"
+            div class="container pt-3 pb-5"
+                t t-out="0"  (Odoo content slot)
+            /div
