SteamGridDB improvement suggestion for Round theme

[rasitayaz]

I rounded up image previews in SteamGridDB pages and flattened the backgrounds. Didn't want to bother with PR so I'm just leaving the CSS here:

.BasicUI #sgdb-wrap #images-container .asset-box-wrap .image-wrap>.thumb,
.BasicUI .sgdb-modal-details .asset-box-wrap .image-wrap>.thumb {
  background: none !important;
  background-color: #3F4F5E !important;
  overflow: hidden;
  border-radius: var(--round-radius-size);
}

.BasicUI .sgdb-modal-details .asset-box-wrap .image-wrap,
.BasicUI #sgdb-wrap #images-container .asset-box-wrap .image-wrap {
  background: none;
}

.BasicUI #sgdb-wrap #images-container .asset-box-wrap .chips {
  margin-top: var(--round-radius-size);
}

Here's a quick before/after:

Let me know what you think.
