The pane sits square on the board's shoulders

Eric's layout call: the first-person pane wears exactly the board's
width, directly above it. A shrink-wrapped column stacks the two, with
the pane held out of the intrinsic sizing (width:0, min-width:100%) so
the BOARD alone decides how wide the column is; the canvas keeps its
aspect as it scales.
