Squashing the 960-wide board texture to a few px averaged the outline away and,
because the GPU picks the mip level from the larger axis, blurred every row too;
the cabinet scales a vector shape and stays sharp. draw_board now builds a
furled board from columns: both rounded corners at 1:1 and the band / panel /
band between them scaled in proportion, each drawn from an 8 px flat slice of
itself and magnified. Narrower than both corners it becomes a solid bar with
the outline columns on either side and the flat centre between them (squeezed
corners left two hollow strokes with nothing between).
