The linked issue was updated after this proposal: its reporter says 72rem/64rem remained cramped and explicitly requests 96rem/80rem. Please align both caps with that revised target, or document why the lower limits remain appropriate.


const INTRINSIC = `clamp(${PREVIEW_RAIL_MIN_WIDTH}, 36vw, 32rem)`
const INTRINSIC = `clamp(${PREVIEW_RAIL_MIN_WIDTH}, 36vw, 64rem)`

// Track for <Pane id="preview">. Folds the intrinsic clamp with a min-floor
// against --chat-min-width so the chat surface never gets squeezed below it.
