/* Logistics Document Intelligence — page-scoped styles.
   Standardized on the existing design system: cs-* (solutions/compare long-form
   pages), the global .btn/.btn-primary/.btn-secondary buttons, .features-grid/
   .feature-card (homepage cards), .cs-table (compare pages), .slx-faq (homepage
   FAQ accordion), and talk-to-sales.css (.tts-layout/.tts-form/.tts-field/
   .tts-toggle) for the embedded form. Only the simulated demo panel and the
   grid helper for 5/6-card rows are new, since no DS equivalent exists for
   either. Shared by the EN page and its pt-BR mirror. */
