Each theme has three pages. Click ◐ (top-right of any page) to toggle light/dark. Resize the window narrow to test mobile portrait. Nav links move between that theme's pages. All keep the existing navigation and functionality — only palette, type, and a signature element change.
Radio instrument console. Amber transmit + cyan receive. Chakra Petch + IBM Plex. RF range-rings signature.
Cartographic survey. Rust + topo green. Archivo Narrow + Inter. Faint contour-line signature.
Live ops console. Monospace-forward, dense, square corners. JetBrains Mono + IBM Plex Sans.
Maps are stylised placeholders (CSS-drawn) to show the themed chrome — filters, markers, popups, legend — not real Leaflet tiles. The production build keeps the real Leaflet map and just restyles its container, popups, and markers.
