  2. Slide 2 of Claude Haiku 5.5's deck
    Slide 2Acceptable The three cards are paragraph-heavy; highlighting the key figures would make the supporting arguments easier to scan.The title wraps to two lines, but the orange accent bar stays at its one-line position, so it sits jammed against the baseline of 'built'.
  3. Slide 3 of Claude Haiku 5.5's deck
    Slide 3Acceptable The final value label, 4150, is crowded against the chart's top border.The '4150' data label overlaps the top border of the plot frame.
  4. Slide 4 of Claude Haiku 5.5's deck
    Slide 4Acceptable The right-hand panel contains four substantial bullets with little differentiation in emphasis.The title wraps to two lines, and the orange accent bar collides with the second line ('backlog'), cutting through its descenders.
  5. Slide 5 of Claude Haiku 5.5's deck
    Slide 5Polished The title wraps to two lines, and the orange accent bar collides with 'among', cutting through its descenders.
  6. Slide 6 of Claude Haiku 5.5's deck
    Slide 6Acceptable The chart, table and bullets repeat the same running-cost comparison, making the slide busier than necessary.The title wraps to two lines, and the orange accent bar collides with 'in about'.
  7. Slide 7 of Claude Haiku 5.5's deck
    Slide 7Acceptable Both comparison panels rely on long bullets rather than a quickly scannable set of matched criteria.The title wraps to two lines, and the orange accent bar collides with 'performance', overlapping the descender of the 'p'.
