/* ==========================================================================
   Ventura WIP System - skin over AdminLTE 3.2
   AdminLTE is an office theme; the factory needs something calmer to look at
   all shift and bigger to touch on the floor. This file does both:
     1. a modern, low-noise back-office skin (cards, spacing, type)
     2. a .shop-floor mode with large targets for scan screens (NF-06 / TS-13)
   No fonts are fetched from the internet - the factory server may have none.
