/* ═══════════════════════════════════════════════════════════════════════
   SiberNebula — MONOCHROME THEME (Ink / Paper)
   ═══════════════════════════════════════════════════════════════════════
   A standalone, pixel-faithful port of ./v2.html. The server serves THIS
   stylesheet (instead of style.css) when SIBERNEBULA_THEME=monochrome, so the
   legacy cosmic theme never competes for the cascade — every value below is
   authoritative for the monochrome skin.

   Mapping note: v2.html uses its own class names (e.g. .btn-new-chat,
   .topbar, .chat-item, .chip, .message.ai). The live app uses different
   names (.sidebar-new-btn, .header, .history-item, .suggestion-chip,
   .msg-group.ai). This file targets the APP's real class names but applies
   v2's exact values, so no markup changes are needed.

   No avatars per message (the app has none) — everything else mirrors v2.
