Ghost/ghost/limit-service/lib/config.js

// NOTE: to support a new config in the limit service add an empty key-object pair in the export below.
// Each type of limit has it's own structure:
// 1. FlagLimit and AllowlistLimit types are empty objects paired with a key, e.g.: `customThemes: {}`
// 2. MaxLimit should contain a `currentCountQuery` function which would count the resources under limit
