Energy (field report: ~3x Chrome drain): - polls skip entirely while the window is hidden/minimized, with one catch-up refresh on return when data is stale; visible-but-unfocused keeps polling (second-monitor case) - all looping animations pause under html.page-hidden (the sidebar flame flicker was a perpetual compositor drain) - default cadence 60s; an explicit stored choice is always honored Currency (field report: set USD, still saw EUR): - memo-served payloads re-applied their embedded stale currency; config mutations now purge the renderer memo and force-refresh, and a switching payload can never overwrite the applied currency - USD default verified end to end Measured: hidden window = 0 new CLI spawns over 5 cadences (was: full polling forever). App 340/340, build + package green.

/**

* Reflect document visibility onto <html> as the `page-hidden` class so CSS can

|
* pause looping animations (the sidebar flame flicker, shimmers) while the window
|
|
* is minimized/occluded — see plain.css. Applies the current state immediately and
|
|
* returns a disposer. Safe when `document` is absent (SSR/tests without jsdom).
