PHPUnit was flagging 18-19 tests per run as "did not close its own
output buffers". The leaks come from Blade — a @once block, a @push,
or a view that throws mid-render leaves ob_start()'ed buffers open
when the test method returns.
Capture ob_get_level() in setUp, then unwind back to that depth in
tearDown. Suite is now green AND clean: 46/46, 0 failures, 0 risky.
