/*
 * hax-about.css — bespoke styling for the /about page redesign (CoWorker design, 2026-05-28).
 *
 * Loaded site-wide from App.razor (this project does NOT use Blazor CSS isolation / .razor.css —
 * every stylesheet is a global file under wwwroot/css/, so the design's requested About.razor.css
 * lives here instead, fully scoped under .about-page to avoid leaking).
 *
 * The page is a tab-style layout with one section visible at a time, driven entirely by the CSS
 * :target selector (the URL hash picks the panel) — NO Blazor interactivity, NO JS. This is what
 * lets /about stay static SSR. :has() handles the active-row styling and the default-to-s1 case;
 * both are supported in all current evergreen browsers (Chrome/Edge 105+, Safari 15.4+, Firefox 121+).
