The lane is now one page open, three commands and one edit: find the dev
server the harness already runs, open it in the harness's own browser,
start with `--dev-url --boot --wait-for-browser`, edit once, reply and
wait with `--then-poll`, and let the helper bake the accept. A wording
with no direction ("better", "improve") asks one vocabulary question
before anything starts. DESIGN.md is a boundary for the variants, not a
mood board. Knobs are out of the lane. Setup step 1 exempts `generate`,
whose start command loads the same context. Reviewed against
writing-for-agents and the house reference style: a search miss never
starts a second dev server, one move per branch, a checkable done line.
