Ellipse simulation, 16 discrete levels per axis

Same six grid sizes as before. Each sample's rx_step, ry_step, and rotation_step is now an integer in 0..15, mapped linearly to its parameter range. Anchor is still picked from interior corners. Opacity is fixed at 20%. Clipping is the grid rect.

selected center • candidate interior corner • overlay (clipped to grid) • overlay pre-clip (dashed)
