September 12, 2025 ⚡️ Spike Solution

Cards are crucial to a software project I am working on. Here a spike solution begins to rework the card ideas, via a clicker-style Mars-base game. This code, co-produced with AI, helps to build a card based dashboard.

This spike solution also explores visual metaphors to track resource exchanges.
