Configures the VPN client branding and default bandwidth limits for the nodal VPN server.

###### Client Branding

Client Accent Colour
  The primary accent colour used in the VPN client user interface. Enter a valid CSS hex colour value (e.g. `#0066cc`). Leave blank to use the default theme colour.
Client Foreground Colour
  The foreground (text/icon) colour used in the VPN client interface. Ensure sufficient contrast with the accent colour for readability (WCAG AA recommends a contrast ratio of at least 4.5:1).

###### Bandwidth Limits

Upload Limit (Mbytes/sec)
  The maximum upload bandwidth per VPN connection in megabytes per second. Default is 100 MB/s. Set to 0 for no limit.
Download Limit (Mbytes/sec)
  The maximum download bandwidth per VPN connection in megabytes per second. Default is 100 MB/s. Set to 0 for no limit.

Bandwidth limits apply per client connection. Adjust these values based on available server capacity and your acceptable use policy.
