   IV Consulting · "BA" theme skin for CASE STUDY pages
   Same neo-brutalist system as landing-ba.css (Plus Jakarta Sans +
   JetBrains Mono, ink-on-warm-white, 2px ink borders + hard offset
   shadows). The case-study pages are self-contained with their own
   inline <style>; this file is linked AFTER it and scoped to
   body.theme-ba so it overrides cleanly.
