+/**
+ * Resolves translation references inside content-template string fields.
+ *
+ * Templates carry raw strings on disk. Consumers that want translation
+ * call resolve() on each user-facing string. Two conventions are
+ * supported, matching the way the hardcoded wiki templates used __():
+ *
+ *   "t:templates.prd.title"
+ *     The whole string is a translation key. Resolved to the locale's
+ *     translation.
+ *
+ *   "{{ t:templates.prd.author }} Gloria Folaron"
+ *     Substring substitution. Every occurrence of `{{ t:KEY }}` is
+ *     replaced with the locale's translation, leaving surrounding text
+ *     intact. Whitespace inside the braces is tolerated.
+ *
+ * Resolution happens at consumer-call time so the current request's
+ * locale is honored — caching the parsed template per-locale would
+ * be the alternative but adds complexity without a real win for
+ * content templates (cold-path, single resolve per page render).
+ *
+ * Implemented as a static utility because there's no per-instance
+ * state. Callers don't need to inject it.
