/* Floating side buttons (Upload SAP CV ... Promote my CV, shown from 1282px): still frosted glass, but the backdrop is
   blurred more and mostly desaturated. With the site's light blur, the yellow hero stars (moving with the mouse,
   parallax) showed through as yellow smears and lines across the buttons (client change list, 28 Oct 2026: "Improve
   my CV ... changes colour and has a grey line through it"); now they show as a soft glow. The tint is bluer and
   stronger to make up for the desaturated backdrop, so over the navy hero the buttons keep their colour (#49526E).
   Firefox keeps style.css (the site turns the blur off there). Loaded after style.css by app/layout/layout.php. */
