  - Separation of server/client tunnels for consistency in iframed/separate view
- More responsive layout tweaks specifically for narrow viewports
  - Lessens UI breakage, particularly for languages with long translated strings
    (ru, de etc)

- Incremental theme tweaks including Arabic (light/dark) & Chinese
  (classic/dark/midnight)
- Fixed placement of "Welcome to I2P" h2 on /home for new users
