/*
  Toolbar layout invariants (do not change without verifying test/toolbar_canary.html):
  - Six action buttons must render on a single row
  - Captions should wrap to two lines under each icon
  - Top toolbar: flex-wrap: wrap; gap uses --action-button-min-gap
  - Action bar: no wrapping; justify-content: space-evenly
  - Action items: auto width; do not force width that causes wrapping
