fixing upside-down image:
use inspect element, add
transform: scaleY(-1);
in the
<div data-v-cd1c09d1="" data-v-a0171230="" class="min-w-0 relative pages-wrap md--reader-pages" ...>
to flip the page container.
it will look like this afterward:
<div data-v-cd1c09d1="" data-v-a0171230="" class="min-w-0 relative pages-wrap md--reader-pages" style="cursor: none; transform: scaleY(-1);">
That way, you won't be confused on where to click.
as to the inverted color, either get used to it, or use 'inverse' extension or something
note:
1. the data-v-cd1c09d1="" data-v-a0171230="" might differ
2. the effect is not permanent and client-side so don't worry about breaking anything
2.5. refreshing the page and/or changing url will resets the change
3. I can't help you if you use mobile phone. Sorry
4. use ctrl+f in the elements tab if you can't find the div. Try searching "min-w-0 relative pages-wrap md--reader-pages"
