impeccable-browser stands in for Chrome via IMPECCABLE_BROWSER. Public
URLs render on Browserless with the key from the Reoclo project
flowstate-tools; localhost and private origins reach it through a
cloudflared quick tunnel that lives only for the scan, with the CDP
traffic rewritten so reports name the local URL. Anything else, or a
failed tunnel or Browserless connection, falls back to local headless
Chrome with --no-sandbox.
It is Linux only, so setup-mac.sh does not link it.
