`brand_pack_write`

Write account Brand Studio pack

Create or update an account-scoped brand pack for an accessible Project: wordmark, organization, palette, fonts, tagline and optional ingested logo. Account IDs are namespaced to avoid collisions with curated packs. Brand is reusable context for programmable scenes, not a fixed visual template. Author a source scene, inspect rendered frames, and iterate before explicitly applying it to a production.
