Readonly[ReadonlykeyThe logical name; the key you set with config set <key> and read with getConfig('<key>').
ReadonlykindAlways 'config' (→ SSM Parameter Store).
Optional ReadonlyschemaOptional value schema (Zod/Valibot/ArkType — any Standard Schema). When set,
getConfig('<key>') returns the schema's output type (typegen inlines it)
and the runtime JSON-parses the stored value. Carried for synth wiring
(the parse flag) and typegen type inference; never serialized to the template.
Marker returned by config — a non-sensitive value in SSM Parameter Store.
