A cryptographically-verified CF Access JWT (signature vs team JWKS + audience +
email allow-list) now counts as the owner, so browser requests through the CF
tunnel don't need the owner token copied onto each device. Fails closed → owner
token remains the fallback (LAN-direct + dev/tests unaffected). Opt-in via
CF_ACCESS_TEAM_DOMAIN / CF_ACCESS_AUD / CF_ACCESS_OWNER_EMAILS.
