i think every day about how cable internet is IP over MPEG. this is a literal fact. DOCSIS sends downstream data in MPEG frames because that's what the cable networks are optimized for and what all the switching equipment understood when cable broadband took off

to increment some counter on the page,
node.innerText += 1
doesn't work (0 → 01 → 011 → ⋯), but
node.innerText -= -1
works fine (0 → 1 → 2 → ⋯)
"Ⱥ" and "Ⱦ" are Unicode characters, which increase in length (from 2 to 3 bytes) when lowercased. Nasty.
