/* ============================================================
   chat.css — Shared Chat Styles
   Used by: contact.html (user side) + chat-admin.html (admin side)
   VERSION: 3.0 — Compact WhatsApp-style bubbles
   ------------------------------------------------------------
   FIXES (v3.0):
     ✅ min-width removed → bubble shrinks to content
     ✅ Tight padding (4px 9px 3px 9px) — WhatsApp-like
     ✅ Meta inline (float right, no margin-top) → no extra line
     ✅ line-height 1.35 (compact)
     ✅ white-space: pre-line (collapses extra spaces)
     ✅ Reduced message margin-bottom
     ✅ Supports both .chat-bubble-meta AND .chat-meta-inline
     ✅ Mobile padding also tightened
     ✅ .chat-text inline (not block)
