PartSourcer devlog #2

Started with a simple annoyance: finding a part that is actually in stock means opening six distributor tabs per line of a BOM. Wrote a throwaway script to poke at the free jlcsearch API and see what the data really looked like. Turned out it has no brand and no datasheet. Decided early to show that as blank rather than show wrong results.

Also built the backend. FastAPI, a swappable data source so the real LCSC API can drop in later.

Also tweaked the frontend a bit. React, inline styles, a loud yellow-and-black look. Then deploy configs, and the site went live on Render.

Implemented a price history recorder, so the data is there later even if nothing reads it yet.

The big addition. The site finally became multi-distributor: Mouser and DigiKey alongside LCSC. Every part now carries a list of offers, one per distributor, and a per-source status so a partial failure shows as a partial answer rather than an error.
