"""
Read-only access to the published content of iammatthias.com. Public and unauthenticated. Every list is a Relay connection; every document carries a cid you can cache against. Cost model: each connection returns at most 100 items (`first` is clamped). Field resolution is O(1) except `Document.body`, which resolves image embeds per document — request it only for documents you intend to read. Limits: a query document of at most 8 KB and 10 top-level fields (aliases count); larger ones are refused with QUERY_TOO_LARGE. Rate limits are Cloudflare's edge defaults, advertised on REST responses via the RateLimit header; there is no per-client quota or API key.
