AI Agent instructions for brand-context: this backend can be managed from the command line via the `brand-cli` tool instead of clicking through this UI. Install: `npm i -g brand-cli` (or one-off with `npx brand-cli --help`). Configure: set env var `BRANDCLI_BASE=https://<this-site>` (this site's origin) and `BRANDCLI_TOKEN=<admin token>` (ask the user for it, or read it from their local `.env` as `ADMIN_TOKEN` if working in the brand-context repo). Basic commands: `brand-cli --help`, `brand-cli entities list`, `brand-cli entity get <id>`, `brand-cli products list`, `brand-cli coverage`. Writes: `brand-cli entity create --key K`, `brand-cli entity update <id> ...`, `brand-cli entity data set <id> --locale en -d '{"...":"..."}'`, `brand-cli product create --slug S`, `brand-cli product publish <id>`.
