Summary from the TLDR Design newsletter

Prototypes built in Figma limit users to predefined paths, making it hard to tell whether a usability failure came from the design or the prototype. Building the Report Broken Site feature directly into a local Firefox Android build with AI produced a prototype with native fidelity to the device. The approach handles branching logic and real network conditions, but demands comfort with terminals, build environments, and IDEs.
