Hey - I've found 1 issue, and left some high level feedback:
- Double-check that the Streamlit version used in all deployment environments supports the
max_selectionsargument onst.multiselect, as this change now depends on that behavior for enforcing the limit.

## 2025-06-17 - Empty State Visual Differentiation
**Learning:** Default informational banners (like Streamlit's `st.info`) for empty states can create a sterile user experience when repeated frequently across many data tables or search results. However, introducing completely custom HTML/CSS violates design constraints. Additionally, standard unicode emojis can render inconsistently or fail completely on Safari.
**Action:** Utilize built-in visual aids via Streamlit's native Material Symbols shortcodes (e.g. `icon=":material/search:"` for search, `icon=":material/menu_book:"` for database views). This improves UX and ensures pixel-perfect, cross-browser compatibility across Safari and Chrome without needing custom CSS.

Pull request overview
Refactors the Team Lab unit multiselect in the Streamlit explorer app to rely on Streamlit’s native selection limiting, improving the input experience and simplifying the surrounding UI logic.
Changes:
- Replaced manual “select >4 then truncate + warn” behavior with
st.multiselect(max_selections=4). - Improved the Team Lab empty-state banner by adding a Material icon and tightening copy.
