 We removed the `.svg` icons from `@db-ux/core-foundations`. This will not affect the `woff2` files required for components. If you still need some `.svg` files you need to install [`@db-ux/core-icons`](https://www.npmjs.com/package/@db-ux/core-icons).

 We needed to remove the brand assets (font & icons) from our [`@db-ux/core-foundations`](https://www.npmjs.com/package/@db-ux/core-foundations) node package. Please follow the guidelines within [DB Marketingportal](https://marketingportal.extranet.deutschebahn.com/marketingportal/Design-Anwendungen/db-ux-design-system/resources/db-theme) on how to retrieve it either as an Inner Source package (DB internal) or to still install the node package from [npmjs.com](https://www.npmjs.com/package/@db-ux/db-theme) (DB external).
