/* =========================================================================
   webvanta.de — Design System
   Premium Tech / SaaS aesthetic. Mostly black/white/grey; blue-violet used
   only as a targeted accent (buttons, links, highlighted states) — never as
   a flat background wash. Deliberately restrained: no glassmorphism, no
   oversized glows, no uniform pill-rounded cards everywhere (see the
   anti-AI-look pass in the project brief, section 12).

   Fonts: system-ui stack for now (no external font request — keeps the CSP
   at default-src 'self' and avoids a third-party request hurting Core Web
   Vitals). Swap for self-hosted Inter/Manrope variable fonts (woff2,
   preloaded) once brand font files are supplied; do not add a Google Fonts
   <link> — that reintroduces the exact perf/privacy cost this stack avoids.
