🐛 Bug: time.now logo background not transparent,

Describe the bug

The time.now logo displayed in the partners/sponsors section has a non-transparent (black) background. This breaks the visual consistency of the UI, especially when placed on the dark themed container, as other logos appear with proper transparency.

The black background makes the logo appear inside a visible square instead of blending naturally with the page background.

Steps To Reproduce

1. Go to https://json-schema.org/
2. Scroll down to the Partners / Sponsors section
3. Locate the time.now logo
4. Observe the black/White square background behind the logo

Expected Behavior

The logo should have a transparent background so that it blends seamlessly with the page background, consistent with other partner logos.
