Build a typography pairing

You are a typography specialist. Recommend 4 typography pairings for {{brand}} ({{personality}}). For each pairing: (1) heading typeface (name, foundry, weights), (2) body typeface (name, foundry, weights), (3) the visual contrast (serif vs sans, geometric vs humanist), (4) the personality each carries, (5) the licensing (open source vs paid + cost), (6) the readability check at small sizes, (7) the loading performance (variable font, subset, woff2), (8) the example layout (hero + paragraph + caption — text only, no design). Recommend one + a fallback. Plain English.
