Prepare the push test
Existing push setup: keep your current push keys. For the v3.0 login update, use Login setup instead.
Open this once on your laptop. Generate two secrets, copy them into Cloudflare, and keep the test access key privately so you can send from the laptop.
Values are generated on this device. This page does not send or save them. Reloading clears them. Generating new values does not change your Cloudflare settings.
Cloudflare → Workers & Pages → my-kanzen → Settings → Variables and Secrets. Add both names exactly as above, with type Secret, for Production. Then deploy the same test ZIP again so the secrets take effect.
Use TEST_ACCESS_KEY in the laptop send form. Do not paste VAPID_PRIVATE_JWK there.
