/* My Child Growth Journey - graphs.
   Marks are thin (bars under 24px, lines 2px), the data end is rounded 4px and the base is square, touching fills are
   separated by a 2px gap of the surface colour, grids are solid hairlines, and text never wears a series colour.
   Series colours are not set here: they arrive with the data from the school's framework. */
