Why is barceloneta.plone.local.less prepending variables from an external url?

[me-kell]

I made a copy of Barceloneta (v2.1.10 as in Plone 5.2.6) and spend hours trying to find out why some of the variables defined in barceloneta.plone.less are not used after compiling less.

I found out that the variable definitions are defined in https://raw.githubusercontent.com/plone/mockup/master/mockup/patterns/toolbar/variables.less and somehow prepended via barceloneta.plone.local.less to the definitions in barceloneta.plone.less.

Please, can someone explain why?
And how to disble loading variables form this external url in a copy of Barceloneta?

it's been a while that i worked with Plone 5, but the general idea was that those variables are normally coming from the Plone database inside the resource registry. Locally (webpack) you have those variables, since you are not having a running Plone when compiling resources with webpack. Thats why the default variables are loaded from Github.
