// UNIT 0 – Sequence Toy
// Title: Star (Explicit Ordered Steps)
//
// PSEUDOCODE (no loops, no logic)
// 1. Move to starting position
// 2. forward 100, right 144
// 3. forward 100, right 144
// 4. forward 100, right 144
// 5. forward 100, right 144
// 6. forward 100
//
// Notes:
// • This reproduces the star shape by writing every step.
// • No loop controls the progression.
// • The walk() timeline ends after step 5.
