/**
 * Two conditions for the proper handling of images with extreme median values (~0 or ~255). Do not edit.
 *
 * On dark  images the median value will be a black pixel.
 * On light images the median value will be a white pixel.
 *
 * So, it prefers to display the light details on dark images and vice versa.
 *
 * Check the "big" hashes for the follow images:
 * - `black-bg-orthocanna-500x500`
 * - `screenshot-dark-purple-flower-1353x851` (look at the text on the screenshot)
