Mobile version institution page

### I developed responsive/flex design suggestions for the institution page in Figma:

**Version 1:**
the museum information is reduced and you can ask for more information on the button.
The information comes as an overlay card and the background gets pass through:

The filter options can be shown by the search and filter icon, it also comes as an overlay:

As a smaller, phone version it would look like this:

--> one question for the icons:
Now they are the same size like the object card icons, but a different size than the history or profile icon on the navigation bar. I like the bigger size better, but when it's close to the navigation bar, you can see that it is a different size. What do you think?

**Version 2:**
the museum information is not reduced:

when scrolling down the information could still reduce like this:

phone version:
here also the icons are smaller, just to compare how it would look like in this size.

Start by reviewing the linked Figma designs alongside the existing institution page. Resolve whether Version 1 or Version 2 should be used, including the icon-size question, with the maintainers before beginning. Done means the selected responsive mobile layout is implemented and its overlays, scrolling behavior, and navigation icons match the agreed design.
