  Direct anonymous HTTPS probes of /.well-known/* on every PBS Biotech host reachable from
  pbsbiotech.com (2026-08-26).
note: >-
  The company's marketing host (pbsbiotech.com, Webflow) serves no /.well-known documents at all — it
  answers every path with a 404 "Invalid .well-known request" stub. Every real document found sits on
  the company's Shopify-hosted online store, shoppbsbiotech.com, and on its customer-account subdomain
  account.shoppbsbiotech.com. Those documents are generated by the Shopify platform for this merchant,
  but they are served from hosts PBS Biotech controls, they name this merchant (UCP merchant_name
  "PBSBiotech", merchant_origin "shoppbsbiotech.com", Shopify shop id 71340753133), and the store's own
  /robots.txt and /llms.txt advertise them. The store is linked from the pbsbiotech.com primary
  navigation as "Shop".
