/* ============================================================
   Factory Portal UI kit — LIGHT theme.
   The friendly, factory-facing front door. Reuses the brand's
   "paper" world (white surfaces, ink text, the one blue, a green
   energy spark) so it stays in-brand while reading clearly apart
   from the dark institutional site.
   Tokens come from the design system (link ../../styles.css first).
