Function: get_card_stylesheet

--Usage--
> get_card_stylesheet(card, set: set)

Get the stylesheet of a [[type:card]].

This is for use in exporter scripts. In card scripts, use the "stylesheet" predefined variable instead.

--Parameters--
! Parameter	Type					Description
| @input@	[[type:card]]		The card you want to retrieve the stylesheet from.
| @set@		[[type:set]]		The set the card belongs to. In an exporter script, this can be ommited since "set" is a predefined variable.

--Examples--
> # Retrieve the card regions from the card's stylesheet
> card_regions := get_card_stylesheet(card).card_regions
