That doesn't answer the question.
[edit] Sorry, was the UI for the Construct actually built using Construct? Do you guys use PixiJS or anything like that as an underlying engine?
The UI was separately developed with JavaScript, it wasn't made in Construct itself (which is mostly canvas-based). The whole runtime is also in-house - we don't use PixiJS or any other libraries, once again it's all our own in-house engine, custom WebGL/WebGPU renderer, etc.
