RetroWebOS
Just pushed a major retro-theming update that dials the nostalgia to 11. This isn't just a skin
change—it's a full immersion retrofit.

What's new in the Retro Edition:
• Authentic CRT curvature simulation (using CSS transforms + filters, not canvas)
• Scanline intensity now dynamically responds to brightness (like real phosphor decay)
• Added 4 vintage wallpapers: IBM green terminal, Apple II monitor, VT100 amber, and RGB composite
artifact
• Terminal now supports true CGA/EGA/VGA color palettes with customizable intensity
• Boot sequence rewritten to mimic POST beeps + memory count + BIOS splash
• Shutdown animation includes realistic power-down surge and fading glow
• System sounds regenerated using Web Audio API to emulate SN76489 and AY-3-8910 chips
• Added "degauss" command to Terminal that temporarily warps the display (with recovery animation)

Favorite feature: The new "Retro Inspector" DevTool
It lets you toggle individual CRT effects (scanlines, curvature, bloom, phosphor bloom, chromatic
shift) in real-time while seeing the performance impact overlay. Pure CSS solutions mean these
effects stay under 2ms frame cost even on integrated graphics.

The architecture tweaks:
• ThemeEngine now accepts spectral power distributions for accurate phosphor emulation
• Audio.js added noise generators for tape hiss and RF interference
• WindowManager gained "persistence" option that leaves ghost images when dragging (like
long-persistence phosphor)
• FS.js now stores theme preferences per-user in IndexedDB with encrypted backup

What I fixed:
• Purple theme had incorrect green channel bleed (was mixing blue+red instead of proper magenta)
• Wallpaper slideshow paused when opening settings menu (z-index conflict)
• Terminal bell sound was too sharp—now filtered through CRT speaker simulation
• Cursor blink rate wasn't respecting system accessibility settings
• Fixed a race condition where desktop icons would momentarily snap to grid on theme change

v0.9 roadmap (Retro polish):
• Add "TV mode" with overscan, color bleed, and RF noise
