Six services, one goes down

Break a service. Which pane shows the outage first?

.status { display: inline-flex; align-items: center; gap: 6px; }
.status::before {
  content: ""; width: 8px; height: 8px; border-radius: 50%;
  background: currentColor;
}
.status[data-state="ok"]   { color: var(--good); }
.status[data-state="down"] { color: var(--bad); font-weight: 600; }

<span class="status" data-state="down">Down</span>

Breathing CTA vs static button

Type a name in each pane. Where does your eye go?

.btn-primary {
  background: var(--accent); color: var(--accent-ink);
  transition: transform 160ms var(--ease-out), background-color 150ms ease;
}
.btn-primary:active   { transform: scale(0.97); }
.btn-primary:disabled { opacity: .5; }

input.addEventListener("input", () => {
  button.disabled = input.value.trim() === "";
});

Let the data prove it's live

Press Record, then Stall the stream.

.rec-dot { width: 10px; height: 10px; border-radius: 50%; background: var(--bad); }
.rec[data-state="stalled"] .rec-dot { background: var(--warn); }
.rec-time { font-variant-numeric: tabular-nums; }

stream.on("chunk", (c) => {
  elapsed += c.duration;
  time.textContent = fmt(elapsed);
  lastChunk = performance.now();
});
setInterval(() => {
  rec.dataset.state = performance.now() - lastChunk > 2000 ? "stalled" : "live";
}, 500);
