/**
 * Vendors the provider brand marks the editor uses, from simple-icons.
 *
 * The provider nodes - ten ways of talking to an OpenAI-compatible API - all
 * carried the same speech-bubble icon, so a list of them was ten identical
 * rows. A brand mark is the one thing that tells them apart at a glance.
 *
 * Only marks simple-icons actually ships are vendored. It removes logos when a
 * trademark holder asks - OpenAI's is already gone - and drawing a replacement
 * by hand would mean shipping something that is not the company's mark while
 * claiming it is. Providers with no mark get a distinct Lucide icon instead,
 * assigned in the node's own @icon.
 *
 *   npm --prefix webui install --no-save simple-icons@16
 *   node scripts/gen-brand-icons.js
 *
 * The paths are copied out rather than imported so the editor does not carry
 * three and a half thousand icons to show six.
