Effect ful computations with Fibers
summary
A small to‑do app is built and iterated until it actually works: synchronous loops become promises, then parallel promises, then a fiber runtime that limits parallelism (example max 5) and supports graceful aborts so cancelled navigation stops work and frees resources. The stack uses Effect (typed R/E/A effects), retry schedules with exponential backoff, dependency injection via service tags, and built‑in interruption and tracing; result is fewer lines of plumbing and predictable concurrency and failure behavior.
