/*
  Pipereply onboarding and settings: design tokens and primitives (visual refinement, approved by Joern 25 Oct 2026).
  Source of the system: v3/design/onboarding-visual/tokens.css. This is the app's own copy; DESIGN.md documents it.

  A light, precise workspace: white sidebar and cards on a near-white canvas, ink text, and one accent that is always
  Pipereply green (decision 27 Oct 2026). The business's own colour lives only in the client roles (--client-*), which
  only previews of customer-facing assets read (public/brand.js derives them contrast-safe). Depth is restrained; glass
  only on the action dock and the phone's top progress bar.

  Everything is scoped to .pr (on <body>) and forced light, so a dark OS or host theme can't turn text pale on white.
