+ * Wait for finishing CSS/Web animations on the page to complete, bounded by a
+ * short timeout.
+ *
+ * Radix UI components animate in via CSS transitions. Playwright's
+ * `toBeVisible()` resolves mid-animation, producing greyed-out or
+ * partially-rendered screenshots. Call this before any `page.screenshot()`
+ * or `locator.screenshot()` to guarantee a fully-rendered frame.
+ *
+ * Looping animations (spinners, pulsing presence dots) never settle, and
+ * animations can also start or restart between sampling and awaiting their
+ * `.finished` promise — so an unbounded `Promise.all` can hang until
+ * Playwright aborts the `evaluate`. Race the settle against a short ceiling:
+ * once the in-flight transitions have had time to land, take the frame.
