The worker only understood one size, `size=tiny`, which meant 32px. It now takes 26, 34, 42 or 52 — double each size on the web app's avatar scale, so avatars stay sharp on retina screens. Anything it doesn't recognise gets the original image, untouched. `tiny` still works and still means 32px. This worker ships separately from the web app, so cached urls and a deploy that hasn't caught up yet keep asking for it. Signed-off-by: eti <eti@eti.tf>
