brand_pack_write

Write account Brand Studio pack

Creates or updates 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. Writing a pack changes no production; a scene that uses it is applied to a production by a separate explicit call.
