# Readiness ping only: send the bypass header alone. Do NOT send
# `x-vercel-set-bypass-cookie: true` here — that makes Vercel answer
# with a 307 + Set-Cookie (to seed the bypass cookie) rather than 200,
# which a cookieless curl can't satisfy. Playwright keeps the cookie
# header (it persists the cookie across requests); this plain curl
# just needs a 200 to know the deployment is live.
