VoidOS Retro - Changelog

[v0.92] - Major Retro-Theming Update

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

Toggle individual CRT effects (scanlines, curvature, bloom, phosphor bloom, chromatic shift) in real-time
Performance impact overlay showing frame cost
Pure CSS solution keeps effects under 2ms frame cost even on integrated graphics

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

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
