/* =====================================================================================================
   NET-DS 1.0 · the network design system (bro.com · dude.com · holydude.com · and any site that adopts it)
   Extracted from bro v2 (graphite / ivory / gold, AI-first, ChatGPT-like) on 2026-10-14.
   Framework-agnostic: plain CSS custom properties + .ds-* component classes. No build step, no JS required.

   HOW TO USE
     <html data-brand="bro|dude|holydude" data-ds-theme="light|dark">   (theme optional: default = brand default)
     <link rel="stylesheet" href="/css/net-ds.css">
   Then either use the .ds-* classes, or map your own components onto the --ds-* tokens.
   Same STRUCTURE everywhere (type scale, spacing, radii, shadows, motion, components); only the PALETTE changes per brand.
   Docs: README.md next to this file.   Owner: dude-redesign agent (/data/scratch/design-system/).
