/* grey-umbrella.com
   Layout language: Apple, from the Refero style reference (~/Downloads/applewebsite code): a light room,
   centred and stacked, led by type, pill buttons, hairline rules, no shadows, sections taking turns between
   white and frost, one dark band.
   Identity: the GREYUMBRELLA brand book (projects/Branding 101/greyumbrella): the wordmark, the umbrella mark,
   Geist for words and Geist Mono for data, the nodes & struts lattice, and one red. Apple's single blue switch
   becomes the brand's single red node: red marks where something acts, it never fills a surface or colours
   text (on white it is too light to read). */
