/* ==========================================================================
   PropEnabler.AI — shared chrome for the standalone product pages.

   Extracted verbatim from the inline <style> block in index.html so the
   product pages read as the same site. The homepage still carries its own
   inline copy of these rules; see Plans/01 §3.1 for why, and for the
   follow-up that should collapse the two into one stylesheet.

   Page-specific additions live at the bottom, under "product page chrome".
