/*
 * Anchored to the bottom of the document (body is the containing block), so it
 * scrolls away with the page rather than riding the viewport.
 *
 * crow.png is 1080x1920 with its top 531px transparent (alpha box starts at
 * y=531), so the bird begins 27.66% down. Showing 26% of the image height:
 *
 *   height    = w * (1920/1080) * 0.26      = w * 0.4622
 *   offset%   = 0.4917w / (1.7778w - h)     = 37.38%   (w cancels out)
 *
 * Cropping rather than letting the rest hang below bottom:0 matters - an
 * overhang would enlarge the document's scrollable area by ~400px of nothing.
