--------------------------------------------------------------------------------
-- Templates
--
-- These are templates used in the module's output. The templates use two
-- different kinds of parameter. Parameters that look like ${parameter} will be
-- replaced with the corresponding value from a data table. Parameters that
-- look like ${@TEMPLATE_NAME} will be replaced recursively by other templates
-- in the templates table. This helps to reduce duplication of template code
-- while also avoiding tricky conditional logic inside templates.
--
-- Templates can contain arbitrary wikitext; wikitext will be expanded on
-- transclusion, and left as-is on substitution.
--------------------------------------------------------------------------------
