 - After collecting all requested resources and screenshots, close any additional tabs/pages opened for capture. This is mandatory; do not leave capture tabs open.
 
 ## Download script usage
-- Use `python download.py --page-id <id> --title "<title>" --urls urls.txt --sources source_urls.txt` to batch download assets. The script generates `<date>` using format `YYYYMMDD`.
+- Primary workflow: run `node run.mjs <page-url>` to capture network requests, screenshot, and download media in one step. This script uses Puppeteer to open a browser with mobile viewport (390×844 @ dpr 3), navigate to the page, capture audio/video/image URLs, take a viewport screenshot, then call `download.mjs` to batch download assets.
+- For manual control: use `python download.py --page-id <id> --title "<title>" --urls urls.txt --sources source_urls.txt` (Python) or `node download.mjs --page-id <id> --title "<title>" --urls urls.txt --sources source_urls.txt` (Node.js) to batch download assets. The script generates `<date>` using format `YYYYMMDD`.
 - `urls.txt` should list the target asset URLs (one per line) already filtered to the requested scope (e.g., media only).
 - Downloads go to `downloads/<date>-<title>-<page-id>/media/`; filenames are cleaned (query/`@!` removed) and extensions retained/guessed; duplicates get numeric suffixes.
 - After the batch finishes, the script deletes 0-byte files, compares against the planned list, retries missing items up to 2 times, and reports any still-missing resources.
 - `urls.txt` is written to `downloads/<date>-<title>-<page-id>/urls.txt` to record user-provided page URLs.
+- The script also deletes the `--urls` input file upon completion.
 
 ## Screenshots
 - Default viewport for screenshots: width 390, height 844, devicePixelRatio 3 (mobile portrait). Do not change unless the user explicitly requests another size.
