/* ==========================================================================
   Design Operations Hub: the product theme for Case Study 05.
   One portfolio design system, multiple product expressions: the portfolio page keeps the site's
   tokens, and everything inside a recreated product frame (.oh) uses this identity: people-centred,
   collaborative planning for a design organization (not HR software, not an admin console).
   Light, slightly warm surfaces; resource cards with initials; capacity bars; timelines; team ↔ project
   relationships; vendor and renewal markers. Sky for interaction; a little signal-orange tint
   (site token --brand-orange #e8501a family) only for time-sensitive renewal markers, never as large fill.
   Status always carries a word. Frames stay light in both site themes and adapt to their own width.
   Synthetic data only. Shared by design-ops-hub*.html and social-src/opshub-thumbnail.html.
