/* =======================================================================
   Ehitale AI Widget — FINAL v6
   Pixel-accurate BotPenguin replication (Images 3 & 4 reference)
   
   KEY CORRECTIONS vs previous versions:
   ✓ Flat vivid blue header (no gradient) with proper rounded corners
   ✓ Chip items CENTERED (emoji + text, centered alignment)
   ✓ Sentence Case chip text (JS handles conversion)
   ✓ Grey filled-circle send button (not transparent paper plane)
   ✓ 8px spacing system throughout
   ✓ Generous bubble padding (16px 20px)
   ✓ Large border-radius on all bubbles
   ✓ Pure white chat background
   ✓ App-like feel, not web-like
   ======================================================================= */
