/* ========================================================= theme.css
   The "operations console" design identity. Loaded LAST so it wins.

   Direction: a churn-management command centre for a CS team working ~1,000
   accounts a day. A fixed dark rail gives the product an identity a plain top
   nav never could; the content sits on a cool slate canvas so white cards and
   severity colour carry the eye. One flat accent (iris) for active/primary/
   focus only — no gradients. Semantic green/amber/red are reserved for health
   and priority and never used as the accent. Fully theme-aware + reduced-motion.
