Our primary logo. Use it wherever there's room for the name. The black and white versions are for
one-colour work only — print, engraving, mono logo strips.
For tight spaces, or where Polar is already named. Its corners are rounded, so don't use it anywhere
that rounds the image again — use the app icon instead.
For anywhere the platform rounds or crops the image itself — social avatars, app stores, Slack,
favicons. The corners are square on purpose, so they don't get clipped twice.
