TenantFont.family

TenantFont.family is the typeface name under which a tenant's font is registered, such as a brand font name. On upload it must match /^[A-Za-z0-9 _-]+$/ and be 1–64 characters. Together with weight it identifies a specific font file: the render engine resolves a tenant's documents to the matching family and weight, and the storage key embeds it as fonts/{tenantId}/{family}/{weight}.ttf. It is part of the unique (tenantId, family, weight) constraint, so re-uploading the same family and weight replaces the file in place.
