  - Existing: resize in-place (requires power off; disk can only grow).
    ```bash
    doctl compute droplet list
    doctl compute droplet-action power-off <DROPLET_ID>
    doctl compute droplet-action resize <DROPLET_ID> --size s-2vcpu-4gb --resize-disk
    doctl compute droplet-action power-on <DROPLET_ID>
    ```

- Add swap (prevents OOM during Chrome spikes)
  ```bash
  sudo fallocate -l 2G /swapfile
  sudo chmod 600 /swapfile
  sudo mkswap /swapfile
  sudo swapon /swapfile
  echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab
  ```

- Harden Puppeteer launch (more stable on small VMs)
  - Set env and pass to `puppeteer.launch`:
    ```bash
    export PUPPETEER_ARGS="--no-sandbox --disable-dev-shm-usage --single-process --no-zygote"
    export PUPPETEER_TIMEOUT=60000
    export NODE_OPTIONS="--max-old-space-size=2048"
    ```
  - Ensure the Node script uses those args:
    ```javascript
    const extraArgs = (process.env.PUPPETEER_ARGS || "").split(" ").filter(Boolean)
    const browser = await puppeteer.launch({
      headless: 'new',
      args: ['--user-data-dir=/tmp/puppeteer'].concat(extraArgs)
    })
    ```

- Give jobs more capacity (Solid Queue)
  - Run more worker processes/containers (e.g., `kamal scale worker=3`) and/or bump threads if you’ve configured them.
  - Keep the web separate from workers if possible (dedicated worker host or at least a separate process).

- Nginx/proxy timeouts (avoid premature 502s while screenshots run)
  - Increase upstream/read timeouts to ≥ 75s if not already.

If you want, I can apply the size bump in `staging-server.txt`, add the swap provisioning to your bootstrap, and wire the Puppeteer env flags. I’ll keep it terse and copy-paste friendly as you prefer [[memory:3389909]].
