Why page speed is user respect

Every 100 milliseconds of web latency directly degrades user trust, increases bounce rates, and harms organic search rankings. Google’s Core Web Vitals have made performance a mandatory technical requirement rather than an optional polish phase.

With the arrival of Interaction to Next Paint (INP) as a standard metric, applications can no longer hide behind fast initial HTML delivery while their main thread remains locked up by heavy JavaScript hydration.

Eliminating layout shifts with aspect-ratio and font display

Cumulative Layout Shift (CLS) is one of the most aggravating user experiences on mobile. When images or web fonts pop into existence late and push reading text downward, accidental taps inevitably occur.

By leveraging modern CSS properties like aspect-ratio, declaring explicit container widths, and utilizing font-display: swap with matched fallback metrics, layout shifting can be brought to absolute zero.

.media-container {
  aspect-ratio: 16 / 9;
  width: 100%;
  background: var(--bg-surface-subtle);
  contain: layout paint;
  border-radius: var(--radius-md);
