I've fixed this issue in PR #6.

Root Cause

OpenCode v1.14.40 uses @opentui/core@0.2.2 which changed the buffer format:

• fg and bg buffers changed from Float32Array to Uint16Array
• The old code wrote float values (0.0-1.0) directly to the buffers
• With Uint16Array, these values were truncated to 0, making the rainbow effect invisible

Fix

Added runtime detection and conversion helpers that handle both Float32Array and Uint16Array formats. The fix is backward compatible.

Verification

Confirmed working with OpenCode v1.14.40:
