Installed Sybil uses `standalone` display, retaining the system status bar where the browser supports it. The viewport keeps pinch zoom disabled. Compact regular-chat replies use the transcript width and the active provider/model appears beneath the title; Agent keeps its existing layout.
Horizontal navigation swipes start on workspace chrome or empty space. Text, tables, quotations, code, controls, existing selections and nested horizontal scrollers keep native gestures, including at scroll edges. Long-press/right-click on transcript text and links uses the native browser menu; the message-actions button provides Fork.
Agent notification settings include separate browser/server failure guidance and an expandable Android / GrapheneOS setup guide. See [mobile QA results and limitations](../docs/mobile-web-qa.md), including how to run the browser fixtures.
