Also, somewhat unrelatedly -- regarding the URL that readerview.html is loading via XHR and hitting 404: that seems to be a "query-parameters-stripped" version of the full URL (only preserving `amp_gsa=1`), and unfortunately that stripping makes the URL 404 as far as the web server is concerned (which I can confirm when I load the truncated URL directly). But if we change the preserved-query-parameter to instead preserve `amp_js_v=a9`, then the URL continues to load just fine!

i.e. this truncated URL that  we're using is 404:
https://www-kron4-com.cdn.ampproject.org/v/s/www.kron4.com/news/bay-area/silicon-valley-tech-executive-sentenced-to-prison-for-covid-testing-fraud/amp/?amp_gsa=1
...but this one loads successfully for me:
