How are membership tiers structured?

Three tiers based on lifetime spend:
• Member: $500+ lifetime spend — 1.25x points multiplier
• Heritage Guardian:$2,000+ lifetime spend — 1.5x points multiplier
• Artisan Partner: $5,000+ lifetime spend — 1.75x multiplier, exclusive artisan recommendations & priority custom slots

Tiers are non-transferable. If account contact info changes, the tier resets to reflect the new account's lifetime spend.
