HBN: Discount Floor Guard

HBN: Discount Floor Guard allows ecommerce merchants to enforce discount floors and markdown limits at checkout without the need for theme setup. The app provides features such as setting checkout guardrails, rejecting conflicting discount codes, blocking checkout violations of rules, creating storewide or targeted safeguards, setting minimum final amounts or maximum markdown percentages, adding exemptions, localizing messages, prioritizing rules, and previewing outcomes in a simulator. Enforcement is done through Shopify Functions.
