## Navigation
The two views now sit inside one curved panel with a full-width toggle at the top, the selected half filled dark green, and the Hugging Face Bio kicker removed. The atlas and the database panels drop their own frames so the whole thing reads as one surface rather than cards inside cards.
## Disclosures
These were out of proportion. Gradio's block padding wrapped the whole accordion, so a one-line title stood 76 points tall with a chunky arrow beside it. The frame is now the button itself, the title carries weight, the arrow is small and muted, and a closed row is 44 points.
## Lineage search
Search takes the English names too, so "sponges", "jellyfish" and "house mouse" all find their taxon. Matches are a list rather than a dropdown, closest first and already selected, with no separate search button: the list follows what is typed, Enter opens the closest match, and clicking a row opens that one.
Ranking prefers whole-name and word-start matches over substrings, so …
Keep the flux into the current selection highlighted (#6)
