Encode the board as blocks of stacked-section columns (C1) and render it as the ASCII-styled DOM grid (C2) with hover highlight and a select emit. Layout mirrors the physical board (Client Satisfaction above Product Architecture; Macroplan above Defect Visualisation, both left of Feature Kanban) and boxes use true ISO 216 proportions (1:√2, each step up scaled by √2). Both views render from the one definition; tests pin section presence, click, hover, layout order, and a snapshot.
