4 h 32 m of screen time a day doesn't sound like much. Itemised, it comes to 1,655 hours a year, 69 days, and 9.4 years of the next 50. We made a free page that prints yours as a till receipt, from a number or a screenshot.

Set display: flex on an element and its hidden attribute stops hiding it. The browser's own [hidden] rule is only display: none, so any display you write wins. We hit it twice in two days on two apps. The fix we use now: put the display on :not([hidden]).
