Changes proposed in this Pull Request

• Update styles of the Jetpack Cloud login page to match the current design.
• Update copy in the header.
• Replace Jetpack logo with Jetpack + WordPress logo.

Important

The end result won’t look exactly as the design does mainly because the font we use in Jetpack Cloud isn’t the same that was used in the design.
