Possible cache confusion between HTML shim and turtle versions of a page

My attempt to reload https://solidos.solid.community/Team/ lead to a blank page and the browser tab favicon showing a "working ... " circle.

Nothing on console log.

Maybe the browser renderer, instead of being given the data browser HTML file, has internally been given the TTL file.

No source file or test is named. Start by reproducing the reload of https://solidos.solid.community/Team/ and inspect the documented request and response headers, especially the 304 response and content type. Done means identifying whether the HTML shim or Turtle representation is returned and resolving the blank-page behavior.
