Each letter has its own scroll position threshold. As you scroll, a rainbow flash sweeps through the text left to right, letter by letter. The Inactive Color and Inactive Scale control how letters look before they're revealed. Active Color is the final settled color. Rainbow Colors is an array you can expand or reorder to define the colors in the flash. Rainbow Spread controls how wide the color burst is across letters at any moment — lower values mean a tighter, more focused flash; higher values make the rainbow fan out across more letters at once. Scroll Distance determines how many pixels of scroll it takes to reveal the entire text, so longer text may need a higher value. Start Trigger sets whether the animation begins when the component enters the viewport ("In View") or when it hits the center of the screen ("Center"). Because this component is scroll-driven, it needs a sticky stack setup so the text stays visible while you scroll through the animation distance.
