+# We created this class as a wrapper to `Liquid::Tag`.  This follows
+# Forem's aspirational architectural decision to create
+# wrapping/insulating classes around our gem dependencies.
+#
+# This pattern is analogous to creating ApplicationRecord models that
+# inherit from ActiveRecord::Base.
+#
+# @note When making a new Liquid tag, inherit from this class instead
+#       of `Liquid::Base`.
