SHA-256: 2ca837b45de184f8

Satori (next/og) cannot synthesize bold weights from a single regular TTF and rejects variable fvar tables. TwinDesk registers all 6 static Outfit TTF weights and hashes every active SKU & pack price so cached 25-day WhatsApp media_id handles auto-invalidate the instant you update a price.
