+# Plan 01 Summary: Item Detail + Candidate Detail Icon Buttons
+
+## What Was Built
+
+Added responsive icon-based action buttons to item detail and candidate detail pages. On mobile viewports (below md: breakpoint / 768px), action buttons display as icon-only with 44px minimum touch targets. Desktop viewports retain full text buttons unchanged.
