- Type `window.__psyHidden` once via global declaration; drop 6 `(window as any)` casts. - `WindowVisibilityProvider` now ORs `window.__psyHidden` into the hidden state (and into the initial state). On WebView2 `document.hidden` does not always flip when `win.hide()` is called, so effects gated by `useWindowVisibility()` can now actually skip creating intervals/rAF instead of relying solely on the per-tick fallback check. - Slow visible-poll from 200 ms to 500 ms (5 → 2 wakeups/s for visibility alone). - Fix stray leading-space indent in `App.tsx` `window:close-requested` comment.
