In `@wrangler.jsonc`:
- Around line 17-20: The wrangler configuration's "routes" key is currently an
object but must be an array of route objects; change the "routes" value to an
array containing the existing object (with "pattern" and "zone_name") so the
schema is satisfied and deployment succeeds, and ensure commas/JSONC syntax
remain valid after converting "routes" to an array.
- Around line 25-30: The KV namespace entry under kv_namespaces with binding
"PROOF_KEY_CACHE" currently uses the placeholder id "TBD" which will block
deployment; replace the id value with the real 32-character hex namespace ID for
PROOF_KEY_CACHE (obtained via `wrangler kv:namespace create PROOF_KEY_CACHE` or
by listing existing namespaces) so the kv_namespaces entry's id field contains
the valid namespace identifier.
