/* ==========================================================================
   APPLE LIQUID GLASS V2 (2026)
   Refined Apple-Quality Desktop Inbox Theme
   - Calm, clean canvas (#F2F2F7) with white and cool-gray solid surfaces
   - System SF Pro stack, dark headings (#000000), secondary (#3C3C43 / #6E6E73)
   - Accent blue (#007AFF) reserved for active selection, focus, primary CTA & outgoing bubble
   - Glass used sparingly: subtle translucent headers/sidebar chrome, hairline border, ambient blur
   - Message bubbles: pure white incoming (#000000 text), Apple blue outgoing (#FFFFFF text)
   - Dense desktop ergonomics preserved: no layout, dimension, or positioning changes
   - Avatar integrity preserved: unmodified background-image/img rendering, solid fallback
   - Strictly scoped to Liquid Glass theme selectors
