Why this journal exists
This journal documents the real trade-offs behind InvoiceCraftly: why it is static-first rather than static-only, how browser-local documents change product design, where Cloudflare Pages helps, and where careful engineering is still required.
The goal is to share enough detail to help other developers and founders make better architectural choices—without pretending one stack is right for every product.
