The daily set

Five real design decisions a day, and the reasoning behind every one — right after you commit to an answer.

Nine levels, a streak that counts only the days you showed up, and a set that ends after five.

One filled button for "Pay now"
Two filled buttons, equal weight
That's the one.
One filled button anchors the decision. "Save for later" becomes a quiet link beside it.
