okhp3-replit-canvas-board

Plan and build a structured multi-frame Replit canvas presentation board — hero rows, labeled zones, iframe lifecycle (building→live), coordinate layouts, and focusCanvasShapes for audience navigation. Use when organising the canvas for a designathon, showcase, or any multi-frame review. Also activate for "arrange the frames", "set up the board", "label the zones", "focus the viewport", or any canvas layout that needs deliberate spatial planning rather than ad-hoc placement.
