Code Search product page revision

[iskyOS]

We'd like to iterate on our Code Search product page (sourcegraph.com/code-search). We have the first iteration design ready for development.

Here is the design, on the page titled "Mockups (we are here)" Figma

The primary changes are:

• We are introducing a new lighter color theme for the page
• We are centering the header, with a new hero image
• We're updating the logo pond to the carousel
• For the 4 primary product sections of the page, we are tweaking some of the copy
• We are reworking several elements at the bottom of the page, including the CTAs
• We're adding customer quotes
