01

Pure Go, 0 dependencies

Go standard library only — 0 external packages, no CGO, no C toolchain. A single binary from go build runs the same on Linux containers, AWS Lambda, and edge runners.

02

12-column grid, no coordinates

Bootstrap-inspired layout. r.Col(7) + r.Col(5) = 12. Layout decisions live in the code — not in a pixel ruler. Rows and columns nest to any depth.

03

CJK, first-class

TrueType font embedding is built in. All 3 CJK scripts — Japanese, Chinese, Korean — render as-is. No tofu (□), no mojibake, no vendor patches.

Speed in numbers
