It matters because speed is no longer just an aesthetic issue. A slow, unstable or heavy page reduces trust, worsens the experience and makes content harder to consume normally.
- Measure loading, stability and interaction under real conditions.
- Optimize heavy resources before adding new visual layers.
- Reserve space for images and elements that load later.
- Review mobile impact, not only desktop.
