I shipped a brand across 30 pages, 3 apps, 3 book covers and a clothing line in one day
Most brand systems are a folder of PNGs and a PDF nobody opens. The mark drifts. Someone exports it wrong for a t-shirt, the knockout becomes ink on ink, and six months later you have four versions of your own logo and no idea which is right.
So I made the mark a Python script instead. lion.py.
Run it with a flag and it emits the correct artifact for the surface. SVG for web. PNG at every favicon and app icon size. Open Graph cards. A garment variant where the face is a genuine knockout rather than printed detail, because screen printing has physics and vector art does not care about physics until it ruins a shirt.
One command regenerated everything: navigation on 30 pages, headers on 17, favicons, 17 individual social cards, three progressive web apps, the clothing prints, and three book covers.
The test for whether you have a design system is simple. Can you regenerate the whole thing from one command? If not, you have a folder.

The brand is DHAHAB. Arabic for gold. The golden standard, which is a promise I have to keep rather than a claim I get to make.
Free tools, three installable apps, and two SIGCSE 2026 papers. See the work or read the facts. Open to Summer 2027 software engineering, AI/ML, and quant internships.
