v0.3.1

• Logo carousel now always rests with a logo on the strip's centre line, at any
  viewport width. It previously started flush left and stepped by the leading
  item's width, so with logos of differing widths whatever landed mid-strip was
  chance — and the edge fade is fully opaque only at the centre, which made an
  empty centre the one position that read as broken. Steps now run centre to
  centre, and items are recycled once they have left the far edge rather than
  on every step. No markup, CSS or setting changes.
