chameleon-tui

Theme-aware animated color post-processing for the OpenCode TUI. Transforms neutral text and surfaces into dynamic metallic gradients, animal prints, neon glows, nature textures, and 50+ visual styles.

Inspired by oc-plugin-rainbow by @kommander.

⚠️ Disclaimer: Some palettes (static, laser, neonflicker, rgbsplit, corrupt, datamosh) contain rapid flashing or high-contrast visuals. Enable CPU Saver to limit animation when not in use.
