Attention!

• I undertand that Floorp is NOT supported on Windows 7/8.1 or lower.

Describe the bug

The 'Recommended by Pocket' section of New Tab has vanilla Firefox's styling, which makes it look kinda awful against new tab page backgrounds.

To Reproduce

1. Be in a region where Recommended by Pocket exists, such as Britain
2. Start a new Floorp profile

Expected behavior

It'll use white header text, and the posts themselves will look way more consistent with the rest of the NTP.
