Impossible to use plugin once again if global mixin used

[BonBonSlick]

Declare global css styles, requried everywhere

Vue.mixin(CSSModules({
  injectAttr: 'mixinClass',
  styles:     { ...stylesFonts, ...stylesCommon },
}),);

Next time we try mixin CSSModules, it rewrites the previous one. Global styles are no available anymore!

So we have to do layout CSS import in every child component, eg PublicLayout (with public CSS eg publicLayout.css) import (publicLayout.css), child component PublicPostPage import (publicLayout.css) etc.
And then apply as docs say

:class="[$style.className, $style.classname...]"
