/**
 * Warms React Router route data and matched route JS without using native link
 * prefetch. React Router's built-in `<Link prefetch>` does both pieces, but
 * its data side emits `<link rel="prefetch" as="fetch">`; Chrome sends
 * `Sec-Purpose: prefetch` for that request and Cloudflare Speed Brain can 503
 * dynamic `.data` routes before the CDN/origin can serve the cacheable result.
 *
 * Keep `.data` warmup as ordinary `fetch()` and JS warmup as `modulepreload`
 * unless production providers stop rejecting `Sec-Purpose: prefetch`.
