Build: Compose VRF

Stand up the VRF example under the user's own Goldsky account. The app listens for a RandomnessRequested(uint256,address) event on an EVM contract, fetches verifiable randomness from the drand beacon (BLS12-381 threshold signatures, verifiable by anyone), and writes it back on-chain via fulfillRandomness(requestId, randomness, round, signature). Trust comes from the stored drand round + signature, not from the caller, so the shared example contract is safe to leave open.

This template supplies only what's specific to the VRF app — how it works and its full source (below). The recommended path uses a shared, fully-unpermissioned RandomnessConsumer on Base Sepolia at 0x6273AB73C95Ba2233281F1eb8aa3b21D9352AD6d, so the user deploys nothing and the Compose smart wallet is auto-created and gas-sponsored.

Step 0a — Load the base skills first

Before anything else — before you answer, ask a question, scaffold a file, or call deployComposeApp — load the two base skills this template depends on:

1. Skill(compose) — the always-on Compose guide: the golden rules (never assume anything about the app on the user's behalf; ask when unsure) and general build guidance.
2. Skill(compose-reference) — the manifest / field / API reference; consult before writing any compose.yaml or task file.

This template deliberately omits those rules and that reference — they are required to build correctly and are not repeated here. Do not proceed until both are loaded.
