Review findings: the mesa forced rock onto the canyon bed, two runners
declared the wrong TEST_COUNT, and the escarpment check could pass on the
slope alone. Canyon gains floor_material, the showcase is re-baked with sand
beds, the contract measures the step across the crest band, counts distinct
ledges, and probes the crevasse against the open plateau. Degenerate recipe
parameters now fail an assert.

Five reference landforms on one 512 m field at 1 m per cell: a stratified
canyon through a mesa, a crevasse between two buttes, a boulder field on
rippled sand, two rock spurs framing a sand channel, and a sinuous
escarpment with knolls on the slope below.
