- * NetworkStatusIndicator
- *
- * Displays the live health of the Stellar/Horizon network with rich
- * interactive loading states:
- *
- * States handled:
- *   "unknown"        — initial, never polled yet → skeleton-like pulse dot
- *   "checking"       — in-flight request → spinning dot + translucent badge
- *   "operational"    — green dot, fast latency
- *   "degraded"       — amber dot, elevated latency
- *   "partial_outage" — orange dot, some services down
- *   "major_outage"   — red dot, critical services down
- *   "offline"        — red dot + error banner with retry + dismiss
- *
- * Variants:
- *   compact  — pill badge for nav/sidebar (dot + text only)
- *   full     — card with latency, ledger, last-checked, and expand/collapse
- *
- * Accessibility:
- *   - role="status" aria-live="polite" for health change announcements
- *   - aria-busy during in-flight checks
- *   - All interactive elements have translated aria-labels
- *   - Reduced-motion: spinner and pulse animations disabled
