+1. In a fresh world, bind a Descriptive Book with Link Panel, Standard Terrain,
+   Plains Biome, Single Biome, Caves, and Rocks pages in that order.
+   Missing weather/lighting/celestial branches may be seed-filled. Travel to
+   the Age and explore several fresh surface chunks: boulders made from one
+   seed-selected full-collision block should appear among the plains terrain.
+   Then explore underground in fresh
+   chunks; the Caves page should add a second cave-carving pass to Standard
+   terrain, not switch the Age to Cave terrain.
+2. Make a second book with Flat Terrain and Caves. The Binder should mark the
+   Caves page unsupported and prevent assembly. Cave Terrain plus Caves should
