Limit group
The basic unit of quota in AIPricingLab: a label, a unit, a quota, a period, and a list of match rules that decide which events count toward it.

Definition
A limit group has: id (lg_…), label, unit (count / tokens / seconds / cents), quota, period (daily / weekly / monthly / lifetime), anchor (subscription_start / calendar), and match rules (event_type + optional metadata). On track / reserve, every limit group whose match rules accept the event increments. Multiple limit groups on the same plan can match the same event, which is how "premium renders" and "total renders" can both count one Flux Pro render.
Example
lg_premium_images { unit: count, quota: 50, period: monthly, match: [{ event: "image.render", metadata: { model: "flux-pro" } }] }
