After rendering a flatly themed (i.e., switchable between light and dark mode) website containing Python code blocks, I noticed that the Python code blocks were hard to see.
Is this change intentional?
It would be easier to read if they were color coded as before.

quarto 0.9.272

quarto 0.9.100

When compared to the syntax highlighting on GitHub below, does it look like the syntax highlighting is too close in color rather than broken?

````qmd

title: test
theme: flatly

```py
import pandas as pd
pd.read_csv("test.csv")
```

```r
library(readr)
readr::read_csv("test.csv")
```
````
