/*
	On recommendation from @valentine195.
	Config based on @jdanielmourao's Sanctum theme esbuild setup.
	(https://github.com/jdanielmourao/obsidian-sanctum)
	Further based on https://github.com/damiankorcz/Prism-Theme/blob/main/esbuild.config.mjs

	Usage:

	Dev build
	$ node esbuild.config.mjs

	Prod build
	$ node esbuild.config.mjs production

	Dev build for one system only (pf2e or bnb):
	$ node esbuild.config.mjs <system>

	Dev build for one system only (pf2e or bnb), output to outfile:
	$ node esbuild.config.mjs <system> <outfile>
