/*
 * One stylesheet, hand-written, no build step.
 *
 * The page is a few hundred words and a list; a framework would be more bytes than the content
 * and a dependency to keep patched for the privilege. System fonts for the same reason -- a web
 * font is a second request and a flash of nothing, on a page whose whole job is to be read.
 *
 * The colours are the logo's, read out of Graphics/groundvis-small.svg rather than picked to go
 * with it: the deep navy its tile is filled with, and the mint its lettering is drawn in.
 *
 * Dark throughout, and no light variant, because that mint is a colour for dark grounds. On white
 * it fails contrast at every text size -- so a light mode would have to substitute some other
 * teal, which is a second palette that is not the brand's, maintained alongside the one that is.
 * The logo is a dark tile; the page is the same dark.
