/**
 * Unity AI Lab — Apps Shared Theme (gothic redesign chrome)
 * Creators: Hackall360, Sponge, GFourteen, Alfreddo, Red
 * https://www.unityailab.com
 * unityailabcontact@gmail.com
 * Version: v2.1.6
 *
 * Slim utility layer for the 8 app demos. The heavy lifting lives in:
 *   • redesign/shared-tokens.css — palette, fonts, font-faces (single source)
 *   • redesign/variations.css    — `.vD-nav-*` styles (matches GothicNavbar)
 * Both are auto-loaded by apps/shared-nav.js, so per-app HTML stays lean.
 *
 * What this file DOES:
 *   • Background ambience (.unity-background-overlay + .unity-red-streaks)
 *   • Scrollbar + selection theming
 *   • Body padding for the fixed gothic navbar
 *   • Legacy .unity-* utility classes still referenced by app pages
 *     (.unity-btn, .unity-card, .unity-panel, .unity-input, .unity-select,
 *      .unity-textarea, .unity-chat-container, .unity-message-*, .app-* etc.)
 *
 * What this file NO LONGER does (moved upstream):
 *   • :root token declarations           → redesign/shared-tokens.css
 *   • @font-face Trajan Pro                → redesign/shared-tokens.css
 *   • #unity-nav-wrapper Bootstrap navbar  → redesign/variations.css `.vD-nav-*`
 *   • Navbar scroll-state JS               → apps/shared-nav.js
