 * Mobile-first. Pixel art is only ever scaled by whole multiples with image-rendering: pixelated:
 * the strip frames are 64x40 art stored at 6x (384x240), so they appear at 256 (4 px per art
 * pixel) or 384 (6 px); the bots are 16x16, shown at 48 (3x). Level colours: LV1 grey,
 * LV2 green, LV3 blue, LV4 orange (#FF8A3D, the same orange as the "Level up" nav button).
