 * intrinsic dimensions the browser resolves background-size: auto against the
 * positioning area and stretches one 256px tile over the whole viewport, so every
 * noise cell lands on roughly four device pixels and reads as low-res mush rather
 * than grain. Explicit background-size then tiles it 1:1, and the 2dppx rule
 * halves the CSS tile so one noise cell maps to one device pixel on retina
 * instead of two. Single octave: the extra octaves fractalNoise adds are
 * low-frequency, which is the blotchiness, not grain.
