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 540 sites (6.5%) with 400 to 799 elements, 99% pass field INP at a 82ms median, and the 24.8% between 800 and 1,499 elements reach 98% good INP (95ms median). Once the document tree crosses 1,500 elements (67.6% of sites, 5,574), good INP drops to 91% and median INP rises to 119ms.
