Description of the problem

At https://codesandbox.io/examples/package/@stencil/core

The text color inside the search box at the top right of the page is a super-light almost-white gray on white background, making it impossible to read.

How has this issue affected you? What are you trying to accomplish?

search for something at https://codesandbox.io/examples/package/@stencil/core

To Reproduce

1. go to https://codesandbox.io/examples/package/@stencil/core
2. Click on the search box at the top right of the screen
3. type something

Expected behavior

I should be able to read what I typed

Observed behavior

It's impossible to read what I typed because the text is almost white on a white background.

Also the blue text of the link just next to it to the right: that's slightly more visible (at least you do see there's something there) but still way too difficult to read.
