/* ============================================================================
   M2 Labs — Serial & Inventory Management
   "Forge" UI · v7 — a dark command-center: deep charcoal-blue canvas, glass
   cards with hairline light, copper-hot accents, display numerals, and
   restrained motion. Dark only — the app has no light mode.
   The entire app is driven from this one file — class names are shared across
   every template, so visual changes here cascade everywhere.
