A remote image allowlist pattern.
Patterns are declared with URL-shaped strings such as
https://images.example.com/** or https://**.amazonaws.com/bucket/**.
Hostname wildcards follow Astro's semantics:
*.example.commatches one subdomain level.**.example.commatches any subdomain depth.
Pathname wildcards also follow Astro's semantics:
/assets/*matches exactly one nested segment./assets/**matches any nested path below/assets/.
