Advanced Prompt for Sticky Reveal Stacking Card Components

Act as a Lead Interaction Designer. Engineer an advanced 'Stacking Cards' editorial scroll interaction in React utilizing Framer Motion. As the user scrolls vertically, [CARD_COUNT] distinct data cards should pin to the `sticky top-0` position of the viewport sequentially, with subsequent cards appearing to physically slide over and bury the previous ones. Utilize `useTransform` to dynamically reduce the scale of underlying, covered cards to [SCALE_FACTOR] (e.g., `0.9`) and apply a darkening [OPACITY_GRADIENT] to simulate deep Z-axis depth. Calculate a programmatic offset logic where each new card's `top` margin is offset by [STACK_SPACING] pixels to create a visible layered deck. Utilize the `whileInView` prop for the initial fade-in entry, and strict `useScroll` linkage for the stacking physics. Ensure the parent wrapper calculates enough padding to accommodate the total sticky duration without overlapping standard document flow.
