/* ========================================================================= HTML element demo — tech-demos/usermedia-html-element.php Loaded after base.css and tech-demos.css. Scoped copy of the Hugo static/css/usermedia-html-element.css: - every rule is prefixed with #usermedia-html-element - the :root tokens live on the wrapper, so base.css keeps its own --ink/--line - the global body, h1 and h2 rules were dropped - section 0 neutralises base.css components that share a class name here (.card, .status, .why) and the base.css
