   Learning Success — "WHAT MAKES LEARNING SUCCESS DIFFERENT"
   Page-unique layout for patterns/why-different.php.

   Editorial / manifesto page. Reuses tokens (tokens.css) and the
   shared component base (components.css: .ls-pattern gives Lexend
   body + Fredoka headings). Everything here is prefixed .ls-diff-
