/* ============================================================================
   vyntratech.ai — marketing landing page (v2 candidate)
   Companion stylesheet for index-v2.html.

   WHY THIS IS AN EXTERNAL FILE AND WHY THE PAGE HAS NO style="" ATTRIBUTES
   ---------------------------------------------------------------------------
   The page is served from the app container under /site, and the app emits a
   Content-Security-Policy for that prefix (backend/app/security/headers.py).
   The app-wide default currently allows 'unsafe-inline' for styles, but this
   page deliberately does NOT rely on that: index-v2.html declares
   `style-src 'self'` in its own <meta> CSP, and a browser enforces the
   INTERSECTION of every policy it receives. That means the page is correct
   under the current policy AND stays correct if 'unsafe-inline' is ever
   dropped from the app-wide value — which is the direction a hardening review
   pushes, not away from it.

   Practical consequence for future editors: there is no escape hatch. A
   one-off `style="margin-top:8px"` will be BLOCKED, silently, and the page
   will render subtly wrong in production while looking fine in a local file://
   preview. Every visual decision lives in this file. Per-item variation that
   would normally be an inline custom property (animation stagger, for example)
   is done here with :nth-child instead.

   Script is `script-src 'self'` for the same reason: see landing-v2.js.

     6. sections, in page order
