# Northlight Supply — instructions for AI agents

> Quiet tools for deep work.

## About
Northlight Supply exists for the two hours a day when the phone is in the other room. We stock a short shelf of desk goods — notebooks that lie flat, pens with real weight, mats and trays that keep a desk quiet — and we test everything against one question: does it help the work, or is it decoration?

Most of what we try doesn't make the cut. What does, stays. Our notebook paper hasn't changed since the first run, and the task lamp on our own studio desk is four years into its shift.

Buy less. Buy once. Get back to work.

## How to read this catalogue

- **Sitemap:** https://northlight-supply.btab.app/sitemap.xml — every product and content page.
- **Catalogue page:** https://northlight-supply.btab.app/products
- **Product pages:** each product has a canonical URL of the form `https://northlight-supply.btab.app/products/<name>-<id>` and embeds schema.org `Product` + `Offer` JSON-LD (name, price in AUD, availability, SKU, brand, images) that you can parse without executing JavaScript.
- **Product JSON:** append `.json` to any product URL — `https://northlight-supply.btab.app/products/<name>-<id>.json` returns the same schema.org Product + Offer document, plus a `purchase` block: `enquiry_only` (sell-by-enquiry, do not treat as add-to-cart), `agentic_checkout` (currently false) and the `url` where a human completes the purchase.
- **Merchant profile:** https://northlight-supply.btab.app/.well-known/ucp
