into a `price` signal (initial value 0) and a `trend` computed: "up" when the price rose since the previous value, "down" when it fell, "flat" otherwise (keep the previous value in the class). Render "<price> <trend>" in <p class="ticker">.
Each exercise pairs a worked example with a twin problem to solve in a real editor; the tests run the moment you do. Interview mode hides the example: solve it from memory, without the hint or the solution, and it counts as solved cold. Progress is saved in your browser, and in your account if you sign in.
