+2026-10-05, Lilleman auf Larv. Serves goal 5.1. Goal 5.1 says everything outside `{…}` prints
+exactly as written, yet `{{` prints `{`, `}}` prints `}`, and a lone `}` is a load error naming
+`}}`, as the README's Format string section states. The maintainer ruled the escape implicit in the
+goal: the braces belong to the `{…}` syntax, so the goal names no exception and a lone `}`
+stays an error. Valid while a template escapes a brace by doubling it.
