Review Comment:
   The helper matches with equals, but the production code removes with 
ACCEPT.equalsIgnoreCase(...). So if the default headers ever carry accept in 
different casing, the prod code removes it while this helper can't see it — and 
the test would still pass. Please use equalsIgnoreCase here, and add a case 
where defaultHeaders() uses "accept" lowercase to prove the removal is 
genuinely case-insensitive.
