Subject: [PATCH] CI: install the browser the prerender pass needs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

pnpm build ends in prerender, which drives a real chromium. Without the install
step the build failed on its very last action, after typecheck, the contract
gates and the tests had all gone green — the most expensive place to discover a
missing dependency.
