Block Arrows

Up down arrow callout

"shape": "upDownArrowCallout" draws PowerPoint's upDownArrowCallout preset. The PPTX export writes it as a native shape with its adjust values, so it stays editable in PowerPoint.

Search words: arrow, label

Frame

A shape block takes the largest frame of 1:2 (width to height) that fits its cell, centered; set aspectRatio for another. Text inside is fitted to the preset's text rectangle and never set below the readability floor.
