On the Subframe mobile landing page, scrolling down smoothly drives a pinned interactive illustration. As the initial hero copy scrolls out of view, a central gray card pins in the viewport. Inside, a tactile 3D black token with the Subframe icon animates and rotates into a miniature retro-styled physical display terminal. Continued downward scrolling swaps the display screen content from a visual UI mockup into syntax-highlighted code, while accompanying narrative headings ('Designers build visually', 'Engineers pull code') slide and crossfade into position directly beneath it.
