A pinned scroll feature section for a heritage house built on the scroll-rail component, set on a dark surface: the heading, intro, an Arrow Pill and an underline link open a century-long timeline that travels sideways as the page scrolls. Each milestone pairs a photograph of its own size and proportion with a very large light year numeral, a short title and one sentence, all hung on a continuous hairline with a dot per year. Older photographs are printed in monochrome or faded tones, each photograph drifts inside its frame, numerals drift against the travel, and text brightens as its milestone reaches the middle. A thin progress line along the bottom fills with the scroll. Reduced motion turns the timeline into a plain horizontal scroll.
