/* videoplayback/css/header.css
   Shared header styles for BOTH markups:
   - header.inc.php / index.php: .cs-header__row, .brand, .actions, .btn, .cs-searchbar__*
   - older/alt: .cs-header-shell, .cs-brand, .cs-actions, .cs-pill, .cs-themebtn, .cs-iconbtn

   Goal:
   - Make headers look the SAME on index.php and videoplayback/page.php
   - Token-friendly (light/dark) without importing index.css
