/* Synchron — styling. Dark "night ops" console: deep navy surfaces, cyan for
   structures/map furniture, amber for RF. Mobile-first; the panel is a
   full-screen sheet under 1024px and a fixed sidebar above it. */

/* ============================================================================
   Palette: BORG's cyberpunk tokens (BORG css/style.css `:root.dark-mode`) mapped
   onto Synchron's own token names, so every rule below re-colours without being
   rewritten. Values are byte-for-byte BORG's — see synchron-app skill § theme.
   Deliberately NO pinks: BORG's `--danger`/`--accent2`/`--violet` are muted clay
   and slate, and the base theme's pink radials were overridden the same way.
   The MAP itself stays neutral (no neon tint) — that was the owner's choice.
