WARNING!
Since 2022-01-14 v. 1.4.10 this plugin no longer supports$mreactive statements and PostCSS since they are not needed
in the maintainer's projects! However, this increases the overall build performance and in case you do not use Meteor
reactivity in Svelte components, you may benefit from using this version
[BREAKING CHANGE] Properly handle css compiler option, $m and PostCSS support dropped
