Nineteen entries at the top of a long page are scrolled past once and then
unreachable. A fixed column stays put and scrolls on its own. Below 66rem there
is not room for two columns, so it collapses to a bar with a toggle — a
checkbox, so the page still needs no script to navigate.
The wordmark's dot was a circle at a guessed x, which drifted from the n
whenever the reader's serif was not the one it was measured against. It is a
full stop in the same text run now.
