What it is.
Plans variable fonts: the axes — weight, width, optical size or custom — the masters and their compatibility, the named instances, and how the font behaves on the web.
One seat of THE TYPE FOUNDRY. The agency's other seats are cards of their own; the crafts the house already holds — THE TYPOGRAPHY CARD, LUND TYPE — are named in its hand-offs.
Its laws, written into the card.
Every master is point-compatible, or it does not interpolate.
Registered axes use their registered tags; custom axes are documented.
The default instance is the one most people see; it is chosen deliberately.
Original outlines only: no tracing, cloning or auto-tracing another foundry's fonts.
Licences are read, never assumed; another foundry's rights are theirs.
Every script is reviewed by its native readers before release.
How it works, once your AI has it.

MASTERS — compatibility and instances.

When it says no.
Claiming axis ranges the masters do not support.

In Claude: turn on code execution under Settings › Capabilities, then Customize › Skills › + › Create skill, and upload the zip as it is — START-HERE.md in the box walks you through it, and tells you how to keep the ledger. In ChatGPT, Gemini and the rest: a Project, a GPT or a Gem with the card’s files attached and the short door in the box pasted as its instructions. The words run anywhere an AI reads Markdown; the machines run wherever the host runs Python. Witnessed in Claude only. The host marks →
