Crowdstreet Domain Security

method: probed
source: live DNS/TLS/HTTP probes of apis.yml hosts (0-working/probe-domain-security.py,
  plus manual probes of the app/API/help hosts, which are not reachable from apis.yml
  link properties alone)

notes:
- HSTS is absent on the marketing site, the investor application and the API host;
  only help.crowdstreet.com sets Strict-Transport-Security (max-age 2592000, 30 days,
  below the 31536000 commonly required for preload).
- No CAA records and no DNSSEC on crowdstreet.com.
- DMARC is published but the policy is p=none (monitor only), so spoofed mail is not
  rejected or quarantined.
- 'Wildcard DNS caveat: status., trust., support., developer. and docs.crowdstreet.com
  all resolve and return the same 858-byte investor-portal SPA shell. These are catch-all
  responses, not real status/trust/developer surfaces, and must not be scored as such.'
