Description
Describe the problem
The Debian packaged version of bslib shows two errors of the test suite. We are running the test suite with this script. This leads to

Research direction
Reproduce the Debian test run from debian/tests/run-unit-test and inspect the failures in test-theme-base-colors.R around lines 368 and 374. Read tests/testthat/helper-css.R to trace why the generated CSS is empty; done means identifying the Debian-specific cause and making both theme-color expectations pass.
