//
// `topWarmUrls` returns absolute URLs that are high-value SSR pages: the core
// listing/hub roots plus the Hyderabad city/zone/locality landing pages (which
// hit the most expensive D1 queries and benefit most from a warm KV cache).
//
// `warmCache` issues a plain GET for each URL (no cookies, so the request is
// anonymous and the edge-cache write path is eligible). Individual fetch errors
// are swallowed — a 404 or a network blip should not abort the whole warm run.
// The caller (the `scheduled` handler) wraps the call in `ctx.waitUntil` so it
// doesn't block the response path.
