/* The site header, in Forecast City's clothes.
 *
 * Forecast Flakes dresses as Forecast City does, the way Forecast Points already does
 * (forecast.city/theme/tokens.json): cream atlas paper, a white-bordered guide-sign
 * wordmark, a plain-text primary nav whose current page is green with a sign-yellow
 * underline, the 4 px sign-yellow rule under it, and a monospaced strip below that for
 * the rest of the network and the data's provenance.
 *
 * Green is the chrome. Blue — the six-inch band of the NWS snowfall scale — stays the
 * colour of the data, never of a button. The markup this styles is written into every
 * page by tools/chrome.py, from one template, and into every generated product page by
 * ingest/products.py through the same function. Light only, as every page on the
 * network is.
