/* ════════════════════════════════════════════════════════════════
   ARCHIVE (Oct 2026): styles for the retired homepage pieces, kept only
   for their lab pages in the component library (lab.html): the grey bio
   plate and its unfolding letter (js/bio-letter.js) and the pixel cat
   (js/cat.js). Extracted from css/styles.css at commit 2ed49e4, the last
   version with both on the homepage. Loaded AFTER styles.css, by lab
   pages only, so the live site carries none of it.
