/* ==========================================================================
   Pagadian City — Hybrid AI Chat Widget
   --------------------------------------------------------------------------
   Brand-aligned: Sangguniang Panlungsod navy (#1e3a5f / #0f2744) + gold
   (#d4a017). Display headline uses Playfair Display (already loaded by the
   public landing). Body Poppins (already loaded).

   Design principles applied:
   - NOT a generic round purple bot. Launcher is a "civic seal pill" that
     reads as official, with a small gold ribbon and the city's monogram.
   - NO emoji-as-icon. NO trust-gradient (purple→blue). NO Inter on display.
   - One accent (gold) used twice max per panel.
   - Glassmorphism scoped to header only — body keeps high contrast.
   - Dark theme is the public-portal default; widget bg is a deep navy
     #0f2744-derived plate so it doesn't fight the homepage backdrop.
