Header logo narrow

********** IMPORTANT ********** Do not delete or rename this image. The header logo is very clumsily hacked so as to point directly at this address, ignoring the logo specified in the site settings. Whatever image is saved here (i.e. https://www.gradunion.cam.ac.uk/files/images/header-logo-narrow) will be displayed in the header on narrow screens. Do not edit unless you're sure you know what you're doing.
