- Inline <svg> is not an LCP candidate; on mobile the tagline is hidden so the
logo was the only large element -> NO_LCP. Serve the mark as
/images/branding/splash-such.svg and render it via <img> (a valid LCP
candidate, painted from SSR HTML).
- Transition: start the cross-fade on click (shimmer plays as the splash fades
into the content) and shorten durations 1.2s -> 0.8s; snappier and blended.
- Tracer target back to the midpoint (computerX+0.5, computerY+0.5).
