  "description": "A rule can carry an 'else' branch that fires when its condition is false, so an if/else is a single rule instead of a rule plus its negated twin (compare 13-if-else-append.json). 'tier-perk' sets a badge either way. Separately, 'grant-discount' offers a discount to everyone, and a lower-priority rule withdraws it for small orders with 'removeOutput' — undoing an earlier rule's write.",
