/* ==========================================================================
   Sowia — landing page styles
   --------------------------------------------------------------------------
   Design tokens ported from the app's design system (ds-crm-app/src/constants/
   theme.ts) so the landing feels like the same product:
     - Brand indigo  #6C63FF / deep #4F46E5 / soft #9A8CFF
     - Cyan accent   #22D3EE
     - Success green #34D399
     - 4pt spacing scale, soft radii (10 / 16 / 22 / pill)
   No framework, no build step. Mobile-first, progressive enhancement:
   the page is fully readable and usable without JavaScript.
