The goal is a deterministic, minimal runtime bundle that satisfies a strict CSP (no unsafe-eval ) an
Handlebars 4.8: Proposed change to default whitespace‑control setting

Constraints: the change must not break existing templates that rely on current whitespace handling, and it should be compatible with the precompilation workflow that require
