Five rules across the four pages put type into --serif. Four of them
render; one is dead. Twenty-one live instances in total, every one of them
reproduced below with the real sentence from the real page at the real size —
no lorem, no isolated glyphs.
Leave a note on any instance. Notes save as you type and survive a reload, so you can walk the page in passes. Copy notes dumps everything you wrote as plain text for handing back.
