/* ---------- Organiser logos (footer of every page, partners bar on the home page) ----------
   Partner marks keep their own colours: the token rule is for JAGP's own design, not for partner logos. The colour
   files go on light grounds, the one-colour white files on dark ones. Never recolour, crop, stretch or add effects:
   only the width is set, the height follows the file. Balanced by equal area: the IEEE Student Branch lockup (3.74:1)
   is drawn at 0.75 x the height of the RAS chapter mark (2.12:1). --h is the RAS height; clear space is at least
   a quarter of it on every side. */
