Bjoern Lietzke updated the portal user interface assets for the statabs-test/indikatoren repository by replacing existing SVG content with new, manually crafted SVG definitions. He added three SVG assets to the images/portal directory, focusing on improving both the visual quality and maintainability of the portal interface. His work centered on asset management and SVG, ensuring that the updated assets would support more consistent UI presentation and facilitate easier future updates. Although the scope was limited to a single feature over one month, the changes provided a foundation for faster UI iteration and streamlined asset handling within the project’s frontend architecture.
