intro: |
  **Cape Storm Lighthouse, 1950s. A winter gale.**

  You took shelter in the old lighthouse when the storm hit. Then the lamp went out.
  Through the rain, a cargo ship's lights are heading straight for the reef.

  One of you climbed up to the gallery. The other is in the cottage with the keeper's books.
  The radio between you crackles. **Relight the lamp. Save the ship.**

    title: The Lens
    narrative: |
      The lamp is lit, but the lens has to turn at the right speed or the ship won't recognise the light.
      The clockwork wants you to set the flash interval in seconds.

            *A huge glass lens around the lamp. Around it are **4 bright "bullseye" panels**, evenly spaced.

      answers: ["10"]
      hints:
        - Each full turn of the lens sends out one flash per bullseye panel.
        - 4 flashes per 40-second turn.
        - 40 ÷ 4 = 10 seconds.
      successText: |
        **10 seconds.** The beam sweeps out across the water. The ship's horn blares, but it's still heading for the reef.
        They don't know where they are.

      Across the bay, another lighthouse is blinking. If you can name it, you can radio the ship its exact position.

      successText: |
        **Bird Rock.** You radio the ship: *"You're between Cape Storm and Bird Rock. Turn to port, now!"*
        A long pause. Then the ship's lights swing slowly away from the reef.
        One last job: lock the lamp room so the storm can't blow the lamp out again.

  successEnding: |
    **60.** The storm door locks with a clang. The lamp burns steady, sweeping the sea every ten seconds.

    At dawn, a battered cargo ship limps into harbour. The captain sends a crate of oranges up to the lighthouse
    with a note: *"To whoever was on watch last night. Thank you."*

    **You saved the ship!** 🌊🔑

    A horrible grinding sound from the reef. (It's a game. Everyone made it to the lifeboats. Try again?)
