/* pluginsolarlondon.co.uk
   London's problem is not sunlight, it is permission. More flats, more leaseholds,
   more conservation areas and more balconies than anywhere else, and the balcony is
   the one surface the new rules exclude.

   Structure is a consent chain: who has to say yes, in order, before anything goes
   up. Nothing else in the network is built as a sequence of gatekeepers.

   Strong red and a deep blue on cool concrete, with a condensed display. Unused
   elsewhere. */
