Overview

Runtime configuration.

Class references are held by NAME, never as Class objects. Retaining a reloadable application class here would pin that class and its whole constant tree past every development reload, and would serve a stale class after the host reloads its code.

#print_stylesheet ⇒ Object

Stylesheet(s) the standalone print document loads — a name or an array of names. Defaults to the gem's own so print output is correct without host configuration. A host whose bundle does not include this gem's CSS should list both, e.g. ['app', 'nti_receipt_builder'].
