/* ============================================================================
   TG SYSTEM v3 — content-page design system (Store + Resources + future).
   Direction (owner, 2026-06-20): match the TG /series/ "Disciplined Retro OS"
   in-OS look — a 90s beveled workstation desktop, NOT a flat black webpage.
   Rules: NO solid-black fills (warm dark gray), every section is a beveled gray
   "window" with a CDE title bar, ONE red accent, crisp 2px square bevels,
   3 fonts: Anton (headings) + Inter (body) + VT323 (chrome/labels/mono).
   Mobile-first. Homepage / TG series / terminal are NOT styled by this file.
