Superpowers with Signals
summary
Live codes a superhero character generator that actually works: app state lives in a service as many signals, name and backstory bind to writable signal templates via inject, powers derive from name with computed, and metrics are individual signals updated by a metric editor. The team writes roughly seven signals and dozens of computed values in ~15 minutes, adds a computed total and remaining-points cap to prevent overflow, and proves the UI stays reactive and performant.
