How DOM tree size taxes style recalculation and layout during interactions

Every time a user taps a menu, filters a grid, or toggles a class, the browser recalculates styles and layout across affected DOM nodes. Across 2,350 sites (41.8%) with 400 to 799 elements, 97% pass field INP at a 72ms median, and the 36.1% between 800 and 1,499 elements reach 96% good INP (79ms median). Once the document tree crosses 1,500 elements (15.0% of sites, 842), good INP drops to 94% and median INP rises to 88ms.
