// versionado e imutável, ver crates/daemon/build.rs), rede sempre para
// `/api/*` (dado dinâmico, nunca deve ficar preso em cache). O nome do cache
// carrega o hash do build (`__CACHE_VERSION__`, substituído em build.rs) — a
// cada build com conteúdo novo, o cache antigo é descartado no `activate`.
