func Handler ¶

func Handler() http.Handler

Handler returns an http.Handler that serves the SPA. For any path not matching a static file, serves index.html (SPA client routing).

Caching is split so a fresh build is ALWAYS picked up on the next load:

• assets/* are content-hashed (e.g. index-D1r1BErK.js) → immutable, cache forever.
• index.html (and sw.js / manifest / icons) → no-cache, so the browser revalidates and never pins a stale index.html that references last build's asset hashes. Without this, a normal reload kept serving the old bundle and code fixes never reached the user — only a hard-refresh did.
