- Replace gray->cool-steel, blue/indigo->cerulean, red->sweet-salmon, yellow/amber->wheat
- Dark sidebar: sidebar/footer use cool-steel-800 bg, text lightened for contrast
- ~11,600 color replacements across ~99 files
- Update tests for new color class names
- Create WeathermapLive module at /weathermap with 60s auto-refresh
- Extend Topology.get_topology_for_weathermap with bandwidth utilization data
- Add WeathermapViewer JavaScript hook with color-coded edges:
* Green (0-30%) → Yellow (30-60%) → Orange (60-80%) → Red (80%+)
- Display throughput/capacity labels on edges (e.g., '847 Mbps / 1 Gbps')
- Add utilization stats dashboard with link count by usage level
- Support full-screen mode for NOC displays
- Integrate with existing dark mode and responsive design
- Add navigation links in sidebar and mobile menu
Technical implementation:
- Leverages existing Capacity module for interface utilization calculations
- Extends topology edges with utilization_level, utilization_pct, throughput_bps
- Builds on NetworkMapLive foundation with enhanced edge styling
- Auto-refresh via Phoenix PubSub and 60s timer
- Filter support for high/critical utilization links
