/* ================== RETRO SITE THEME (Library / Blog pages) ================== */
/* Applies the same Win95 desktop look as index.html (teal desktop, gray bevel panels,
   window chrome) to library/blog pages. Loaded ALONGSIDE the page's existing stylesheet
   (blog.css / style.css), never replacing it — article typography, the centered/narrow
   text column, callouts, code blocks, images are all untouched. Self-contained: does not
   depend on css/retro.css (which is scoped to index.html only). */
