This is the document that breaks lazy readers. Real photographs, every one a different height — wide horizons, tall portraits, a whole gallery in one file.
Scroll down and back up, fast. Watch two things:
- The scroll bar doesn't twitch. Its size is right from the moment the document opens, because every photo was measured before a single line was laid out. Readers that measure images as they arrive make the page grow underneath you, and the line you were reading slides away.
- Memory stays flat. Photos far behind you quietly hand their memory back and reload when you return. Their space is never given up — that's the difference, and it's why nothing shifts.
Then jump to the end with ⌘↓ and come back. Same story.

holding Moby-Dick.
The largest animals that have ever lived, photographed from above by a marine sanctuary survey.
Forty tons leaving the water. Zoom in — the photo stays sharp, and it costs nothing while it's off screen.
A tall photograph, in a document full of wide ones. The layout doesn't care.
The century Melville was read in, photographed at anchor.
Not every photograph is a postcard. A NOAA team documented this whale during a disentanglement response — the same camera, the same ocean, a different day.
If the scroll bar is the same size it was when you opened this, and your place never jumped, the whole point of the app just happened — quietly, which is the idea.
