// The brand kit .zip — the second item in the report's download menu, and the
// one the launch review found pointing at a route that does not exist on this
// origin.
//
// Assembled in memory (lib/report-downloads.mjs) and zipped in memory
// (lib/zip.mjs), because a serverless function has no `zip` binary and this
// app carries no dependencies to add one. What comes out is the panel's kit:
// brand-summary.md, the palette as CSS and JSON, the fonts, the ranked logos
// (with the files it could fetch), the untouched capture, and a manifest that
// accounts for every byte in it.
export const runtime = "nodejs";
export const dynamic = "force-dynamic";
// Fetching a handful of logo files over HTTP is the only slow part, and it is
// bounded by its own per-request timeout.
