Usage discounts (comp tastings)

Membership tiers now support usage discounts — a new benefit type built for comp tastings and other capped, per-member perks. You can define how many uses each tier gets, which products or collections the benefit applies to, and how the allowance resets (calendar year, rolling, anchored to subscription frequency, or specific dates). On POS, staff see a member's remaining uses in the member panel and the discount is applied automatically at checkout, and Card on File picks it up too — so you can finally enforce "4 free tastings a year" without relying on tribal knowledge or generic discount codes.
