error: could not compile `wifi-densepose-desktop` (lib) due to 1 previous error

[ruvnet]

Root Cause

All 5 icon files in crates/wifi-densepose-desktop/icons/ were RGB PNGs (no alpha channel). Tauri's generate_context!() proc macro requires RGBA PNGs and panics at compile time if they're not.

file icons/32x32.png
# Before: PNG image data, 32 x 32, 8-bit/color RGB, non-interlaced
# After:  PNG image data, 32 x 32, 8-bit/color RGBA, non-interlaced

Fix

Converted all icons to RGBA:

• 32x32.png → RGBA
• 128x128.png → RGBA
• 128x128@2x.png → RGBA
• icon.icns → RGBA
• icon.ico → regenerated with RGBA
