Dopamine Cost Simulator
Scroll the mock feed the way you normally would. The panel on the right tracks what the pattern is costing your working memory — and every 15 seconds an interruption tests whether you can still switch tasks cleanly.

Coach note
Nothing here says scrolling is bad. It says undirected scrolling is expensive: each blip and interruption forces a task switch, and the reload cost is what you feel later as “I can’t focus.” Notice how much slower your matching gets as the depletion index climbs — that’s the measurable part.
