 <!--
-  PageShell — Shared card wrapper for pages in a carousel.
-  Provides: header, five preset widths, maximized mode.
-  Used by workbench (AppPage) and todo (TodoPage).
+  ModuleShell — Canonical card shell for every Mana module surface.
+
+  Replaces the old PageShell + AppPage split. A single component serves
+  both rendering paths:
+
+    variant="card"  — width-sized, sits in a PageCarousel next to siblings.
+                      Window actions (close / move / resize / maximize)
+                      belong here. This is what the homepage and the
+                      legacy per-module carousels (e.g. /todo) use.
+
+    variant="fill"  — fills the main content area. Sub-routes
+                      (/picture, /picture/generate, /library, …) use
+                      this. Back-button replaces the close button when
+                      a backHref is provided. No carousel window
+                      actions.
+
+  Visual chrome (paper-texture, soft border, rounded corners, shadow,
+  header bar) is identical across both variants so the homepage and
+  sub-routes read as the same system.
