详细描述

In-memory terrain heightmap: a dense float grid (row-major, index = y * width + x) materialized from a TerrainSampler or filled by hand.

Use generate() to sample a TerrainSampler per-pixel, height(x, y) / sampleBilinear(x, y) to read values back, and toGrid() to classify the heights into a semantic Grid2D ready for tilemap generation.
