  2. Slide 2 of Gemini 3.8 Flash's deck
    Slide 2Acceptable The title names the section rather than stating the recommendation.Square-cornered red and green accent bars sit across the rounded tops of the cards, so the card corners look clipped and misaligned

    Slide 4Polished
  5. Slide 5 of Gemini 3.8 Flash's deck
