The language products are written in.
Not a catalogue — the grammar. Every kind of thing, the questions it answers, and the words that answer them. Drawn as a structure, read in plain English.
A microwave oven is a kind of powered product. It earns its place by answering questions its parent does not: cavity capacity, heating mode, microwave power output and turntable diameter. On top of everything every product answers — like material, brand, and weight.

Kinds →
The tree of product types — from Product down to specific things — each answering its own set of questions. Drawn, with the parent it refines.
02Properties →
The questions a product can answer, grouped by concern: identity, measurement, pricing, compliance, media, availability.
03Vocabularies →
The words that answer them — materials, colours, brands, units. Closed where physics bounds them, growing where sellers coin them.
04Blueprint →
How the language is built and why — the laws it obeys, and the one rule that decides a kind from a value.
// read live from the pool — every page is server-rendered, structural, and shows the model exactly as it stands. The language is being seeded now; it grows as you watch.
