Lens presets

A lens saves just the way you're looking (the levels, filters, and mode) without touching what you're looking at. Applying one never moves your ticker, panes, or splits, which is what makes lenses reusable: build a "0DTE morning" lens once, apply it to any name.

On Expo, lenses are per pane, so a four-pane grid runs four of them. Editing a preset updates every layout that points at it.
