/* ==========================================================================
   PBXB64 Help — Unified Skin "PBXB64 Dark" v2
   --------------------------------------------------------------------------
   One stylesheet for every generated help page, all languages.
   Design constraints:
   - Must render correctly inside the Windows HTML Help (CHM) viewer, whose
     engine is legacy IE: NO flexbox/grid/sticky/custom-properties reliance.
     Modern enhancements are layered so they degrade gracefully.
   - High contrast, readable at 100% zoom, printable (print = light theme).
   Palette (keep in sync when theming):
     bg        #181818   panel #101010   raised #252525
     text      #f0f0f0   muted #9aa0a6
     accent    #4ec9b0   accent-hi #5df0d0   link #7ecbff   link-hi #aaddff
     ok        #4CAF50   warn  #ff9800       danger #ff6b6b violet #d4aaff
