/* =========================================================
   CureGuard CLOUD HMI V1.3 — CG DARK INDUSTRIAL (#33)
   DEFAULT stylesheet since 1.3.63 (promoted 2026-07-31);
   styles_cloud_v1.2.css stays as the fallback UI's sheet.

   Design rules of this theme:
   - layered near-black surfaces, crisp 1px borders, NO blur shadows
   - corner radius capped at 2px (sharp edges)
   - weight 900 reserved for DATA VALUES; labels are 600
   - color = status only; one accent (purple); data values in mono
   - legacy var names (--cg-purple, --status-*) are REMAPPED here so
     var() references inside JS-injected inline styles inherit the
     dark theme automatically.
   ========================================================= */
