v2.6.0

What's New

New Sensor Support (#7)

• CO (Carbon Monoxide) — life-safety alerts with critical red severity
• PM10 — coarse particulate matter (WHO 2021 thresholds)
• PM1 — ultrafine particulate matter
• PM0.3 — particle count (p/0.1L)
• All 4 support indoor + outdoor comparison

CO Safety Alerts

• CO > 100 ppm → "CO Danger — Leave Area" (critical red, highest priority)
• CO > 35 ppm → "CO Warning — Ventilate Now" (critical red)
• CO > 9 ppm → "CO Elevated — Ventilate"
• CO warnings are never suppressed by outdoor conditions — it's a life-safety concern

Reorganized Visual Editor

• Primary 4 sensors (CO₂, PM2.5, Humidity, Temperature) always visible — zero clicks to configure
• Additional Sensors collapsible section for power users (CO, HCHO, tVOC, PM1, PM10, PM0.3)
• Outdoor Sensors collapsible section for all 10 outdoor entities
• Advanced collapsible section for AQI entity, graph history, temperature unit

Graph Display Order

Safety-first ordering: CO → CO₂ → PM2.5 → PM10 → PM1 → PM0.3 → HCHO → tVOC → Humidity → Temperature
