/* JunaHub design tokens — calm utility palette
   Geist + Geist Mono, neutral grays, single steel-blue accent.

   Token hierarchy (light theme; dark theme overrides where needed):
     surfaces  bg / bg-alt / bg-sunken / bg-elev / overlay
     ink       fg / fg-muted / fg-subtle
     edges     border / border-strong
     accent    accent / accent-hover / accent-bg / on-accent
     semantic  success / warn / danger        (+ -bg, -on)
     states    focus-ring / shadow-sm/md/lg/xl
     imp       imp-bg / imp-bg-nested / imp-fg / imp-pill-bg / imp-pill-init-*

   All values are oklch so contrast/lightness are predictable across hues.
   .jh-paper is a separate surface that does NOT theme — it stays paper-white
   for PO previews, completion reports and other "print" surfaces. */
