Notes

The Ngrok website offers a variety of SVG icons, but their preferred one is the blue 'ngrok' icon with the color #02228e.
Ngrok does make use of a smaller icon n as shown in the brands page, but this is only used for the favicon and literally nowhere else.

Given the original icon's simplicity and single color, I set the terms plain, plain-wordmark, and original-wordmark as aliases with the base being "original".

Paths need to be unified since it's an alias for the plain and plain-wordmark versions.
Excellent use of aliases btw!
