/* video-player.css — the self-playing course player (PHP-FUNCTIONS/functions-video-player.php, js/video-player.js).
   Built from theoildesk.com's player.css. Self-contained: every colour, size and space is a --vp-* variable defined here
   with theoildesk's values (navy stage, amber accent), and the buttons and small text the player uses are styled inside
   it at zero specificity (:where), so a site's own button styles win and a site without any still gets these. A site restyles it by overriding the variables on .page-play.
   Slide image fills the frame, subtitles in a translucent band, progress bar in the accent colour, one row of controls.
   Works at 390 px: the stage keeps 16:9, subtitles scale with the viewport, controls wrap. */
