Explicit code style

Prefer code whose control flow, errors, types, and absence semantics are visible at a glance. Apply these conventions without exposing implementation details or changing contracts. Follow the current repository's AGENTS.md and tool-enforced rules when they add stricter constraints; never use that as a reason to weaken the API JSON rule below.

Multiline control flow

Write if, for, and while statements with braces and a multiline body where the language supports them. Avoid single-line control-flow bodies, even when they are short. This keeps future edits safe and makes branches easy to scan.

  return;
