   CA PRO Toolkit - caprotoolkit.in, the video tutorials page (tutorials.html), v1 (2026-10-12).
   Loaded after styles-v39.css and built only from its tokens. The player's chapter list reuses the
   video guides' .guide-steps rules and the video frame their .guide-player; a problem with a video
   is drawn by fix-v1.js in the site's shared box. Nothing here styles another page. Like every site
   stylesheet the version is in the name: once published, this file is never edited in place.
