Windmap probe

Run this inside XCTrack's Web page widget, not just in Chrome, the WebView has its own storage and its own rules. Run it in Chrome too and compare: the numbers will differ, and that difference is the finding.

Test a tel: link

Should open the dialer with 041 620 91 06, do not press call. If nothing happens, XCTrack's WebView swallows non-http schemes.

Asks the browser not to evict our data under pressure.

Then fully restart XCTrack and reload this page. If the blob is still listed under Storage, offline map packs are viable.

PMTiles needs byte ranges. Must report 206. Note: python3 -m http.server does not support ranges and will report 200, a false negative. Only trust this test against the real host (GitHub Pages, Netlify, or a tunnel).

Checks whether wind APIs can be called with no proxy.
