Details

Browse Source 
- Replace scroll-snap with sticky pin wrappers (120vh dwell per step)
- Steps stick at 25vh while user scrolls through wrapper height
- IntersectionObserver now watches pin wrappers, clears data-step on exit
- Sidebar animates in at step 0, hides when scrolling away
- Remove aggressive scroll-snap-type from html
- Tablet/mobile: fallback to relative positioning with fixed heights
