I think the emphasis is not displayed correctly (in Windows).

I think it should be:

strong, b {
    font-weight: 800;
}

Hello, Thank you for try Misty Theme out!

I've made some tests before and finally selected 400 as body font weight, 500 as strong/b font weight on Windows(300, 400 on macOS respectively).
For me, it turns out that 500 & 600 render as same thickness(see first shot) and 700 & 800 render as same thickness(see second shot):

As you can see in these 2 shots, whose font rendered is 'Segoe UI', 500 & 600 are a little thin and visually subtle, while 700 & 800 are rather thick and visually obstructive, damaging entire feel.

For this reason, I choose 500(may also be adjusted to 600 if needed) instead of 800 as strong/b font weight on Windows.

I'm planning to change font weight to (300,500) on macOS & (400,600) on Windows from (300,400) on macOS & (400,500) on Windows to make it a little more obvious to distinguish between normal & bold text.

I've done some tests and maybe I know where the problem is.

I changed strong/b font weight (line 505 in the 'misty-light-windows.css').

For me, it turns out that 400 & 500 render as same thickness(see first shot) and 600 & 700 render as same thickness(see second shot) and 800 & 900 render as same thickness which is much more thicker(see third shot):

So I think you just need to choose 600 instead of 500 as strong/b font weight on Windows and it will be all okay.

Maybe it's a Windows System problem or something else. I don't know. Hope it helps.
