## pixi.mjs — PixiJS 8.21.0 (MIT)

Topology graph renderer for the admin panel. Self-hosted on purpose: the panel
must not depend on a CDN at runtime (the CTF network is air-gapped during the
event, and a CDN outage would take the topology view down with it).

Provenance and upgrade path:

    npm pack pixi.js@8
    tar xzf pixi.js-8.21.0.tgz
    cp package/dist/pixi.min.mjs panel/static/vendor/pixi.mjs

Use `pixi.min.mjs`, **not** `pixi.min.js`. The `.js` bundle is an IIFE that
discards its return value and exports no global, so it cannot be loaded with a
plain `<script>` tag. The `.mjs` build has real named exports and is loaded via
`await import('/static/vendor/pixi.mjs')` in `static/topo_pixi.js`.

Loading it dynamically (rather than a `<script>` in every page) keeps the ~800 KB
parse cost off panel loads that never open the Topology tab.
