+## Archive Reason
+
+<!-- SECTION:ARCHIVE_REASON:BEGIN -->
+
+Archived after validation showed the proposed optimization is not correct with the current
+LiveView stream rendering structure.
+
+Collection and wishlist render either `<.record_grid>` or `<.record_list>` behind
+mutually exclusive `:if` branches, and both components consume the same `@streams.records`
+stream. LiveView stream entries are consumed after render and the existing DOM holds the
+streamed children. When the display mode changes, the previously mounted stream container
+is removed and a different stream container is mounted. Without re-running
+`stream(:records, records, reset: true)`, the newly mounted container has no queued stream
+entries to insert, so only its static empty-state node remains and `only:block` displays
+“No records yet”.
+
+The DB reload avoided by this task is therefore also the step that rehydrates the stream
+for the newly mounted container. A future optimization would need a different rendering
+shape, such as keeping both containers mounted or avoiding conditional stream container
+replacement, before removing the reload.

+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+
+Reverted the proposed `handle_set_display/2` change and archived this task as not
+actionable in the current UI structure. The reload is required because grid/list toggling
+replaces the mounted stream container.
