   HSE MANAGEMENT SYSTEM — DESIGN SYSTEM
   ───────────────────────────────────────────────────────────────
   Grounded in mine-site safety signage: ANSI/ISO safety colors carry
   real meaning (amber=caution/open, red=hazard/overdue, green=
   compliant/complete, steel-blue=informational/in-progress) rather
   than generic UI red/green. Every stateful card or row carries a
   "status spine" — a 4px colored left edge, the one signature motif
   threaded through the whole system, borrowed from how physical
   safety permits and tags are colour-filed on site.

   Dark graphite is reserved for chrome (sidebar, topnav, login) —
   the working content area stays on warm paper, not dark-mode-
   everywhere, so dense tables and forms stay easy to read for a
   full shift.
