Every route handler was written as one dense semicolon-chained line
(server.mjs's main handler was over 2000 characters wide) — real
width, not a VSCode wrapping artifact. Ran Prettier to break statement
structure into properly indented multi-line code; left template
literal string contents untouched since Prettier doesn't reformat
inside those, so the large HTML-generating return strings are still
single long lines by nature, just no longer compounded by unformatted
surrounding JS. Verified: tests pass, node --check passes, and the
app renders identically before/after (screenshotted the diff).
No devDependency added — npx prettier@3.9.5 pinned in the new scripts
keeps the zero-runtime-dependency pledge intact; formatting is a dev-
time concern only.
