The guest first session should be one clean loop before signup

The current guest preview is close, but it still asks the learner to interpret the interface a little too much.

A stronger first session would be almost scripted: open the sample lesson, highlight the active subtitle, prompt one word click, then let the guest try one save action that naturally leads into signup. That teaches the product by doing, not by explaining.

If the first two minutes feel obvious, conversion improves for the right reason: the learner already knows what Butterfluent is for.
