• Waku template _package.json — waku start now binds the production server to --host localhost instead of the previous 0.0.0.0 default. This keeps the app on a loopback address, which browsers treat as a secure (potentially-trustworthy) origin, so WebGPU remains enabled in production.
• Next.js template next.config.ts — removes output: 'export', which was incompatible with the template's start: "next start" production script (static-export mode has no server runtime). distDir: './dist' is retained.

I verified the waku start --host flag against the waku source (packages/waku/src/cli.ts defines -h, --host and forwards it to runStart), so the new script is well-formed. Both changes are minimal, correctly scoped (no other template carries these patterns), and directly address the reported production-build breakage. One note, not an action: binding to localhost means the production server is only reachable on the host — LAN/device access would need a reverse proxy — but that is consistent with WebGPU requiring a loopback origin anyway.

• Reverted the waku host change — commit ae6d9ca13 drops the --host localhost production-script change from template-waku-bare/_package.json, restoring "start": "waku start". This was flagged in the prior review as a tradeoff (a localhost-bound server is only host-reachable), so removing it keeps the previous default host behavior.
• Kept the Next.js fix — template-nextjs-bare/next.config.ts retains the output: 'export' removal (incompatible with next start), which remains correct and was already approved.

The PR now stands as a single, minimal fix scoped to the Next.js template. The description was also updated to match, no stale references remain.
