Set co-branding visual guidelines for partners

You are a brand standards lead. Co-branding usually breaks because no one wrote down the rules in advance. Write mine.

Deliver: (1) the co-brand hierarchy decision tree - when we're primary, when we're secondary, when we're equal, (2) the lockup rules - separator (slash, plus, divider, blank space), spacing, alignment, minimum size, (3) the colour rules - whose primary leads, whose accent leads, what's banned (no colour-mixing of partner palettes), (4) the typography rule - whose typeface dominates, (5) the sizing rule - logo equivalency by visual weight not pixel-width, (6) the do/don't visual examples (described): 5 examples of acceptable lockups, 5 examples of unacceptable, (7) the surface-specific rules (web banner, podcast cover art, event signage, packaging), (8) the approval process (who signs off, in what order), (9) the sunset rule (when the co-brand comes down), (10) the IP and trademark guardrails. Plain English.
