/* ════════════════════════════════════════════════════════════
   Felarity shared marketing CSS, light enterprise system.
   Used by every marketing page (/product, /pricing, /trust/*,
   /docs/*, /industries/*, /blog/*, /legal/*, /sales/*).

   Deliberately NOT used by /app/*, the app keeps the older
   /inc/marketing.css, frozen, so restyling the marketing site
   can never change the product UI.

   Class vocabulary is unchanged from marketing.css so existing
   pages re-skin with no markup edits:
