Formal mown lawn for a disc/ellipse ground cap. Reads the cap's centered UVs, so concentric mow stripes follow the entity's elliptical scale: alternating with/against-nap bands every stripe_width meters, blade grain in arc-length coordinates along the mowing direction, patch and dry-spot drift with bare soil in the driest spots, and a stripe-signed nap lean on the normal plus a velvet sheen that gives rolled turf its two-tone read under low sun.
