   CSD ENGINEERS — SHARED SERVICE ARTICLE DESIGN SYSTEM
   Loaded on all single service pages (is_singular('service')).
   The inline-edited Article body should now contain NO <style>/<script>.
   Per-service accent is driven by body classes added in functions.php:
     body.csd-svc-{post-slug}  -> exact per-service accent (13 services)
     body.csd-cat-{term-slug}  -> category fallback (new services auto-inherit)
   Override any accent here; the article markup stays identical.
