/* ==========================================================================
   YouTube video cards
   ==========================================================================
   Styles the HTML produced by the youtube() macro in main.py (used on
   video reference pages, one card per video). Depends on pathfinder.css
   variables (--bgtan, --pagegold, --titlered, --inkblue, etc.) — load
   after pathfinder.css and admonition.css.

   Note on specificity: admonition.css has a blanket rule
   ".md-typeset .admonition, .md-typeset details { ... }" at specificity
   (0,1,1). Every selector below that targets a bare <details>/<summary>
   inside .video-card is written as ".md-typeset .video-card__summary ..."
   (two classes) specifically to outrank that — a single-class selector
   here would silently lose and leave Material's default border/background
   showing through.
