/*
  WHAT THIS DOES
  --------------
  - Builds an in-page test runner panel.
  - Runs a battery of tests probing GM_xmlhttpRequest options, callbacks, and edge/abnormal paths.
  - Uses httpbin.org endpoints for deterministic echo/response behavior.
  - Prints a summary and a detailed per-test log with assertions.

  NOTE: Endpoints now point to https://httpbun.com (a faster httpbin-like service).
        See https://httpbun.com for docs and exact paths. (Also supports /get, /post, /bytes/{n}, /delay/{s}, /status/{code}, /redirect-to, /headers, /any, etc.)
*/

/*
  WHAT IT COVERS
  --------------
  ✓ method (GET/POST/PUT/DELETE/HEAD/OPTIONS)
  ✓ url & redirects (finalUrl)
  ✓ headers (custom headers echoed by server)
  ✓ data (form-encoded, JSON, and raw/binary body)
  ✓ responseType: '', 'json', 'arraybuffer', 'blob'
  ✓ overrideMimeType
  ✓ timeout + ontimeout
  ✓ onprogress (with streaming-ish endpoint)
  ✓ onload (non-2xx still onload)
  ✓ onerror (DNS/blocked host)
  ✓ onabort (manual abort)
  ✓ anonymous (no cookies)
  ✓ basic auth (user/password)
  ✓ edge cases: huge headers trimmed? invalid method; invalid URL; missing @connect domain triggers onerror
