   Every new rule is prefixed .cb-* so it can coexist with legacy
   inline <style> blocks in index.html and library.html while those
   pages are still running on the old classes. The original
   layout-styles.css content is preserved verbatim at the bottom of
   this file under LEGACY — do not remove until the homepage and
   library rewrites (execution steps 4 and 7) ship.
