The two-finger swipe gesture used for page navigation frequently triggers the pinch-to-zoom function unintentionally. This is a recurring source of friction — the app zooms in mid-navigation, requiring the user to manually reset the zoom level before continuing.

Request: Introduce a Zoom Lock toggle that disables pinch-to-zoom when activated. This should be accessible quickly — either from the toolbar or a floating button — so users can enable it during long note-taking or reading sessions where zoom is not needed. When Zoom Lock is on, two-finger gestures should be interpreted exclusively as page-turn inputs, not zoom triggers.
