All three use the C → D → A narrative. The difference is pacing and how hard the sections hit.
Page tells the story top-to-bottom like a long-form essay. Each section is a chapter. Dark hero → light relief → dark OS vision creates strong rhythm. Works best for someone who reads the whole page.
Split hero: hook headline on left, live-looking terminal output on right. Shows the product in 5 lines before explaining it. Draws in the developer who wants to see before they read.
Explicit chapter breaks with dramatic chapter-1 open — bold headline, minimal copy, maximum tension. Each chapter is a beat. More like a product launch page than a docs site.
