   kernfabrikat – style.css  (v0.2 · Pitchdeck-Redesign)

   Design language: professionalised evolution of the original kernfabrikat
   deck template.
   - deep navy dark slides, near-white light slides, alternating
   - one teal / petrol-cyan accent, two-tone ALL-CAPS section titles
   - generous, consistent slide rhythm
   - diagrams as HTML / CSS / SVG; photographic visuals blended via mask /
     gradient overlays rather than placed as hard image boxes

   Sections:
     1  Tokens (dark default + light overrides)
     2  Reset & base
     3  Typography
     4  Slide scaffolding (slide, inner, head, title, lead, split)
     5  Buttons
     6  Header & navigation
     7  Hero
     8  Vision  (orbit diagram)
     9  Problem (hub-and-spoke, x-list)
    10  Lösung  (dashboard mock, checklist)
    11  Architektur (layer diagram)
    12  Kernfunktionen (icon rows)
    13  Lokal / Hybrid (balance scale, ticks, pills)
    14  Leistungsmodell (cards)
    15  Roadmap (timeline)
    16  Warum (icon cards)
    17  Relevanz
    18  CTA
    19  Footer
    20  Reveal · reduced motion · responsive · print

/* 1. Tokens --------------------------------------------------------------- */
/* Dark-blue premium palette — the whole site (including impressum.html,
   datenschutz.html, 404.html, which share this file) reads from these
   tokens. There is no separate light color-scheme any more: every section
   is a dark blue tone, differentiated only by --kf-bg-main vs
   --kf-bg-section (see the per-section overrides near the slide rules)
   plus spacing/borders/glow. Legacy variable names (--bg, --text, …) are
   kept as aliases so the rest of this file did not need a line-by-line
   rewrite — change the --kf-* values below to retune the whole site. */
