  "longDescription": "This example teaches efficient batch encryption in FHEVM. Instead of encrypting values separately, chain multiple .add*() calls to create a single encrypted input with shared proof. This reduces gas costs, ensures atomicity, and improves efficiency. Learn how to encrypt mixed types (integers + booleans) together and access them via handles array.",
