+Small refinements that did not warrant stages but complete the picture:
+- The kiosk launches from the sidebar's hardcoded "Displays" section (beside
+  Shopfloor Dashboard / TV Slideshow), plugin-gated and opening a new tab -
+  kiosk-style pages belong there, not in the plugin's Information nav.
+- The touch keypad was restyled into a terminal-style card panel (boxed
+  entry display, fixed 3-column grid, press feedback) after the first
+  hands-on review called the initial version ugly. Looks are requirements
+  on a kiosk.

+The overall arc is the lab's closing lesson: the spec carried the build to
+stage 10; every stage after came from deployment and real users. Plugins are
+finished by the floor, not by the spec.
