Griddle v1.0.4

Griddle — a floating panel that authors snappable grid guides in the Rive editor via its MCP server. Deterministic: no agent, no AI.

14 grid types: rectangular (+cell gutters), dot (snap crosses), baseline, brick, isometric, triangular, diamond, hexagonal, polar, 1-point & 2-point perspective, golden ratio, rule of thirds, layout columns.

Requires the Rive editor running with a file open (MCP server on 127.0.0.1:9791).

macOS builds are ad-hoc signed (not notarized). First launch: open the app once (it will be blocked), then System Settings > Privacy & Security > "Open Anyway". Or skip the dance with: xattr -dr com.apple.quarantine /Applications/Griddle.app
