GitHub's YAML issue forms require `description:`, not `about:` (which
is for the legacy markdown templates). GitHub silently ignores forms
with invalid top-level fields, so only the config.yml contact links
were showing in the new-issue picker.
Runs pytest tests/ on every push and PR. Ubuntu runner with
Python 3.11, libmpv, and QT_QPA_PLATFORM=offscreen for headless
Qt. Badge in README links to the Actions tab.
117 tests, ~0.2s locally. CI time depends on PySide6 install
(~2 min) + apt deps (~30s) + tests (~1s).
