"Reading in the factory the books that eventually helped me get out of it" — that's a hell of a backstory for a side project, and it shows. The best tools come from a real, specific frustration rather than a market gap someone identified on a spreadsheet. The 0.86 inversion value being tuned for hours of actual reading rather than just looking right in a demo is exactly that kind of detail.

Thanks, I deeply agree. It's Alan Cooper's concept in About Face, where he says that to design well you need to take the role of the apprentice alongside the master, meaning observe how they work, understand their frustrations before proposing solutions. In my case I was the master and the apprentice at the same time, but it's an approach I want to carry with me.
