Lua error: Module:TNT:172: '''Missing JsonConfig extension, or not properly configured; Cannot load https://commons.wikimedia.org/wiki/Data:I18n/Uses TemplateStyles.tab. See https://www.mediawiki.org/wiki/Extension:JsonConfig#Supporting_Wikimedia_templates'''.

This module implements {{if preview}} and {{preview warning}}. It helps templates/modules determine if they are being previewed.

Prefer implementing the template versions in other templates.

In a module to use the main(), you need to pass a frame table with an args table.

For the preview warning, use _warning().
