+  (agent) New material menu for walls and molds. With the Build tool on a wall block or a mold,
+  press F (or click the material chip on the Build card) to open it. Each material shows how
+  much you have, what this piece costs in it and the heat it stands (melts at / burns at /
+  won't melt). Ones you have come first; ones you can't afford are dimmed. R still cycles.
+  To check: Build (3), Wall block, F, pick Clay. Then a mold piece, F again.
