   USE-CASES-PAGE.CSS
   The 3 sections unique to use-cases.php: a dark jump-nav hero,
   an interactive "By Situation" tabbed panel (light), and a dark
   alternating timeline ("A Day With IndiaConnect AI"). Everything
   else on the page (categories, how-it-works, final-cta) is
   styled by sections-v2.css already. Depends on the same root
   tokens in style.css.
