Module:Infobox

Documentation for this module may be created at Module:Infobox/doc

-- Module:Infobox — generic infobox renderer for the Yezur wiki.
-- Emits a floating infobox styled by [[Template:Infobox/styles.css]] via
-- TemplateStyles. Wrapper templates (e.g. Template:Infobox polity) map their
-- own fields onto title / subtitle / image / caption and numbered
-- header / label / data slots, then call {{#invoke:Infobox|render|...}}.
