/*
  THESIS: a named specialist's real ~20-year SAP HR/Time/SuccessFactors track record,
  proved with a live flow diagram instead of an agency feature grid.
  OWN-WORLD: restrained white/near-black + two deliberate accents, Sora across display
  and body weights, hairline borders, pill controls, authored SVG flow motifs in place
  of stock photography or gradient icon tiles. No status-dot/badge conventions, no
  invented methodology framework - real content only.
  STORY: an HR/IT decision-maker sees Core SAP HR -> SuccessFactors -> Integration
  resolve into SAP BTP in the first viewport, reads a named founder's real track
  record as the proof a testimonial section would otherwise carry, and emails.
  FIRST VIEWPORT: left-aligned headline + two CTAs; right, a live animated node-flow
  panel (SAP HR -> SuccessFactors -> Integration -> SAP BTP).
  FORM: brief-pinned (folk.app minimal SaaS world) - direction committed directly,
  no concept roll.
  COLOR: mint (#17a589) carries the SAP HR/SuccessFactors/Integration expertise chain;
  a warm amber (#d98f2b) is reserved for SAP BTP - "where process becomes digital" -
  and the closing CTA, the one deliberate "spark" moment against an otherwise cool,
  systematic palette. Amber is not an AI marker; AI is one BTP capability among many.
