Missing styles in game analysis and studies

### Is there an existing issue outlining your problem?

- [x] I am using the latest version of the provided userstyle.
- [x] I have searched the existing issues and they do not solve my problem.

### What userstyles are you seeing the problem on?

lbl:lichess

### Describe your problem.

As can be seen in the first two screenshots below, some pages in lichess.org are missing styles.

### Attach screenshots.

### Original colors

### What browser(s) are you seeing the problem on?

Vivaldi 7.1.3570.54 (Chrome/132.0.0.0)

### Any additional comments?

I've made my own modifications to improve the coloring (can be seen in the next two screenshot above), but I have only tested it in my own browser and with the mocha flavour. I also didn't modify any of the existing styles and didn't check other pages I don't usually use, so there are surely some improvements to be made. But I hope this snippet can help to improve the existing amazing theme.

```css
/* Main */
header.scrolled {
background: @crust !important;
}

/* Notation */
.result,
.status {
background: @crust !important;
}
line move {
color: @subtext0 !important;
}
interrupt {
background: @crust !important;
}

/* Analysis */
.palantir {
color: @blue !important;
}
span[role="tab"] {
color: @blue !important;
}
povs:not(.printable) {
background: @crust !important;
}

div[class^='advice-summary']:not(.symbol) {
color: @subtext1 !important;
}

/* Study */
.study__player {
background: @crust !important;
}
.study__chapters {
background: @crust !important;
}
button.next {
background: @surface2 !important;
color: @subtext0 !important;
}
.study__metadata,
.study__metadata h2,
.slist tbody tr:nth-child(even),
.slist tbody tr:nth-child(even) input {
background: @crust;
}
.slist tbody tr:nth-child(odd),
.slist tbody tr:nth-child(odd) input {
background: @surface0;
}
.slist tbody th {
color: @subtext0 !important;
}
.study__comment,
.study__message,
.study__multiboard,
.study__share,
.gamebook .comment,
.gamebook .comment::after {
background: @surface0;
}
```

### My own modification

Start with the `lbl:lichess` userstyle entry point and compare the analysis and study pages shown in the screenshots. Review the supplied selectors as candidate coverage, then check the affected pages in Vivaldi; done means those pages receive the intended Catppuccin styling without regressing other lichess pages.
