"""arc_grid — the ARC-AGI 64x64 grid system, extracted as a standalone package.

Bundles two pieces:

* ``arc_grid.arcengine`` — the grid/sprite engine (vendored from arcprize/ARCEngine).
  64x64 grid, 16-color palette, Sprite / Camera / Level / ARCBaseGame, collisions.
  External deps: numpy, pydantic.
* ``arc_grid.rendering`` — the visualization layer (palette + frame -> RGB / terminal).
  External deps: numpy (always), matplotlib (only for the animated display helpers).

Quick start::

    import numpy as np
    from arc_grid import frame_to_rgb_array, COLOR_MAP
    from arc_grid import Sprite, Camera

    frame = np.zeros((64, 64), dtype=np.int8)      # a blank 64x64 grid
    rgb = frame_to_rgb_array(0, frame, scale=4)    # -> (256, 256, 3) uint8

See README.md for details and attribution.
