These [fonts sizez](https://github.com/netguru/help/blob/master/app/assets/stylesheets/settings/variables.scss#L14) were set up by @madsheep some time ago. I've only left them to keep stylesheets back compatible. We're not using such big fonts in new designs so we're gonna introduce new font sizes. Also I'd like to define typography classes/placeholders in [utilities/typography.scss](https://github.com/netguru/help/blob/master/app/assets/stylesheets/utilities/typography.scss).
