    "why": "A page saved with Save As tends to open months later as a blank screen or a spinner that never stops. kage loads each page in real headless Chrome, waits for it to settle, snapshots the DOM, deletes every script and pulls CSS, images and fonts to local paths. `kage pack` then collapses the mirror into one ZIM file (the format Kiwix uses) or a single executable that serves the site itself (about 13 MiB plus the site).",
    "take": "It does one thing, keeping what a real browser rendered minus the code, and finishes in an open format (ZIM) instead of its own.",
    "build": [
      "You could schedule a job that re-renders an internal docs site with `--refresh` into a script-free static copy, or run archiving on a server with the container image that bundles Chromium. The pure-Go ZIM reader and writer (zim/) can be reused on its own."
