A fork with nothing on one side is `if (!user) return` — a reader takes it as a
guard, not as a decision with two sides. Drawn as a branch it costs a column
and a step right, and a handler with four guards (every server handler) read as
four nested branches with three-quarters of the width holding the words
"returns here". It is now one line — the condition and where the code leaves —
with everything below it running because it did not, and the rail stays on its
own hairline. next-saas-starter's `signIn` goes from not fitting the screen to
fitting it.
