Add gradient wallpaper and panel shadows for glass depth

The flat white background is the root visual difference from the
design reference. Replace it with a warm-to-cool diagonal linear
gradient (pink-beige to lavender-blue). Add BoxShadow to both
sidebar and main pane panels for floating depth. Use warmer panel
background (88% white) instead of 62% transparent. Add soft shadows
to active nav items and workspace tiles. Avatar uses gradient
matching the design reference.
