   NOVA GLASS v10 — true "Liquid Glass" pass.
   Loaded LAST among the glass files (after v9, before nova_layout_fix.css) so it
   wins the glass cascade. Scoped under html[data-theme="glass"] only, so Nova
   Moon (default) is untouched.

   Goal (from the design brief):
     1. Stronger backdrop blur so the colourful background blobs melt behind panels.
     2. Lower panel opacity so the background colours softly shine through.
     3. A thin semi-transparent white border = specular highlight on the glass edge.
     4. A faint, wide-spreading drop shadow so panels float elegantly.
