Static-first frames, HUD layers, terminals, and radar — with optional React only where charts, maps, or motion earn the bundle. Tune the shell globally, then ship your own routes on top.
Prerender by default, islands when you opt in — same tokens and shell across every page.
Composable overlays, no global state machine.
Map, intel, charts — env flags trim weight.
Everything here is MIT-licensed source you can lift into your own project. Docs describe tokens, props, and third-party caveats.
