+**Completion notes (this slice):**
+
+- Implemented on feature branch created from `refactor`: `rep-slice-r5-elements-normalisation`.
+- Added render-only shared fragments under `components/case/representation/elements/`:
+    - `RepresentationTypeSelectorBlock.js`
+    - `RepresentationActionButtons.js`
+- Integrated these fragments into main representation variants only:
+    - `representationAppellant.js`
+    - `representationAgent.js`
+    - `representationInterestedPartyPerson.js`
+- Preserved scope constraints for Slice R5:
+    - kept parent components as logic owners
+    - no submission/update side-effect refactor
+    - no upload service behaviour changes
+    - no payload/route/query/Redux/validation business-rule changes
+    - consultation variants intentionally not normalised in this slice
+- Validation evidence:
+    - `npm run lint` completed (warnings only, no new errors).
+    - `npm run test:reps` completed: **7 passed**.
+    - Manual APP/IP/Agent/LPA checks: **passed**.
+    - Manual EN/CY parity checks: **passed**.
