Klyssa 0.9.2
Preview frame now contain-fits the project aspect, so overlay position and scale match export instead of shifting when the preview box is letterboxed.
Blend modes (screen, add, multiply, overlay, and friends) render in both Canvas2D and WebGPU preview.
Export range honors an explicit start/end from the last export or agent, and filmstrip thumbs share one decoder so pasted copies of the same clip do not stall playback.
Windows x64 installer. macOS Apple Silicon DMG to follow in a follow-up upload.
