Graph performance: seed node positions to prevent NaN geometry warnings,
cache sprite textures, reduce simulation ticks (120→50 warmup, 300→150
cooldown), cap particles at 2, lower sphere segments, halve label canvas
size, add sessionStorage graph data cache with 60s TTL.
Mobile PWA: add both mobile-web-app-capable (Chrome/Android) and
apple-mobile-web-app-capable (iOS), viewport-fit=cover for notch support,
apple-mobile-web-app-title, safe-area CSS insets on header/body, fix
admin.html missing all mobile meta tags.
