copywriting — write it in the product's own voice

Part of super-ux — see system-map.md. After changes, run python3 docs/brand/lint.py.

First action, every time: read the brand pack. docs/brand/voice.md, terminology.md, and the channels.md record for the surface being written.

No pack? Stop and hand off to brand-voice. Do not improvise a voice. Guessing it and being wrong costs more than the pause, and a product whose copy was invented surface by surface is exactly the drift this layer exists to remove.

The opt-out is spoken, never assumed: "no brand" / «без бренда» — or "draft it" / «черновиком» — is the operator declining this route: write directly and say the pack was skipped on request, never skip it silently.
