   Astra Automation — docs header action bar (AA-8644)
   Variant 1a "Стабильный тулбар" — styles for pydata-sphinx-theme.
   Tokens reused from astra-styles.css (:root --color__base-*, --font__base-astra).
   Collapse is driven by a CSS container query on .bd-header__inner (the

   Unified control height: 40px desktop / 44px (<760, touch). Breakpoints
   900 / 760 / 540. Loaded after astra-styles.css.
