TesseraA design-system-first frontend framework

Tokens, accessibility, variants and docs are built in and enforced at compile time.

The contract is the component

A component declares its anatomy, variants, states and accessibility in a contract. The compiler checks every use against it.

A raw color or an off-scale spacing value is a build error with the nearest valid token suggested, and an autofix when it is unambiguous.

A baseline records today's violations so an existing app can turn enforcement on with zero errors and fail only on new ones.

Single-file components with HTML-like templates, signals, auto-imported components, file-based routing and layouts.

Status: early development (v0.5). @pixelscriptio/tessera 0.5.0 is on npm. See Releases for what exists and the roadmap for what does not.
