The service worker's engine cache key relied on a manual CACHE_VERSION bump that was forgotten across the last two @valknar/vpinball-wasm version bumps, so returning visitors kept getting served old cached vpinball.js/.wasm/.data via cache-first with no revalidation — the origin server itself was serving a correct, matching 0.3.4 set the whole time (verified via headers/sizes against the local build). Split CACHE_VERSION into a manually-bumped SHELL_VERSION and an ENGINE_VERSION that copy-engine-assets.mjs now writes automatically from the installed engine's package.json on every build, so the engine cache always busts in lockstep with the dependency version — no step to forget.
