/* ============================================================
   Qubit Factory · Control Room theme  (drop-in replacement for
   static/mine_levels/user-level-theme.css)
   ------------------------------------------------------------
   This file maps the EXISTING class names in user-levels.html and
   user-level-editor.html to a new "Control Room" visual language
   (granite chrome + LCD counters + physical buttons + hatched
   warning bars), so the HTML markup does NOT need to be edited.
   The repo's JS bindings (#user-pill, #level-list, #stat-public,
   etc.) keep working as-is.
   ------------------------------------------------------------
   Both pages ship an inline <style> block AND <link> this file.
   Since the link comes LAST, the rules here win against the
   inline block for any property they set.
   ------------------------------------------------------------
   ASSET PATHS:
     Expects ../images/granitetile90.png and granitetile85.png
     (already present in the repo).
