+// ToDo not nessisarily an issue with this file but ✅ internal/handlers/template/
+//→ For anything that handles HTTP rendering (RenderError, RenderPage)
+
+//✅ internal/helpers/template/
+//→ For anything that helps render (TemplateContext, pagination, funcs)
+// there for bear usages between helpers and handlers
+//In clean Go architecture (especially following “Package by responsibility”):
+
+//Type	Responsibility	Should access
+//Helpers / Utilities	Pure, stateless logic — e.g. template functions, math, formatters.	Shared logic, no config, no HTTP handlers.
+//Handlers	Own an HTTP concern — e.g. routes, rendering responses, returning templates or JSON.	Injected dependencies (cfg, db, etc.). Should use helpers, not vice versa.
