summary
Shows a concrete PWA build: a tiny dancing‑dots site (hushlittlebaby) of about six kilobytes that replaces a bloated 45 megabytes video, uses a cache‑first service worker and falls back to appcache so it works on older iPhones, and drops a 27 second first load down to 190 milliseconds. Demonstrates HTA/legacy packaging, a web manifest generator, web workers for in‑browser gzip and preprocessors, and advocates IndexedDB for gigabytes of offline storage.
