     * SDD-L09-T11. `handleResize` used to read `window.innerWidth` four times and `innerHeight`
     * once, then call `setWindowSize` with a **new object** — on every single resize event. A drag
     * of a desktop window fires those by the hundred, and each one produced a state object that was
     * never equal to the last by identity, so every one re-rendered the whole subtree. On the survey
     * page that subtree includes a full-viewport `<Confetti>` canvas.
     *
     * Two changes. The measurement is now coalesced into one animation frame, which is the rate at
     * which a change could be painted anyway; and the result is compared field by field, so the
     * common case — a resize that does not cross a breakpoint and does not change the numbers React
     * renders — bails out without touching state at all.
