Upstream ssb-viewer printed it above every page, aimed at people who had arrived at a stray scuttlebutt message and needed context. On cust.ooo the context is the site itself, so it was explaining the wrong thing. Removes the function, all four call sites and the now-dead .top-tip CSS. Adds a "Changing how pages look" section to the README, since the real question was where this lives. There is no template directory - pages are built as strings in render.js with one <style> block - so the answer is "grep for the text you can see", and the table maps each visible piece to the function that emits it. It also records the two things that will bite an editor: hyperscript silently drops attributes it mistakes for DOM properties (why loading="lazy" uses setAttribute), and only text passed through h() is escaped.
