Being able to customize Kagi Assistant' font size will improve accessibility for visually impaired people who struggle to read small characters.
Currently, the UI' font size is 12px while the chat content is 19.2px. The chat is easily readable but the main UI (sidebar, tips, navbar) are much less readable and feel inconsistent with the rest of Kagi' UI.
The UI font size should be uniformed (ideally to match Kagi' search) and the font size defined in appearance settings (https://kagi.com/settings/appearance) should be applied to Kagi Assistant' UI.
