Emphasize key parts of a slide

Emphasis draws attention on the slide to what the presenter is saying. It is added automatically with the automatic script; the finished example has emphasis on 21 lines.

The example is a five-slide briefing deck on the benefits of a generative-AI chat platform for small and midsize companies. It is a sample report produced by DeepResearch in Bestllam (https://bestllam.com), our own service, loaded as it is. The presenter is Sophia.

This example kept the automatic emphasis (red frames and underlines). Here we show how to inspect emphasis and its settings. The Marker look was only previewed, not confirmed.

The first finished example below was made from this deck. The second was made from another deck about growing cherry tomatoes and shows emphasis with different looks.
