/* Forecast Waves — ocean signage design system
 *
 * Same bones as the rest of the network (weather.city, Forecast Eagle, Forecast
 * Euro, Forecast Canada): warm paper ground, Overpass, the same card/rule/shield
 * components. What changes is the identity colour and the mark, and neither
 * choice is arbitrary.
 *
 * The headline is **Deep Water Teal** (`#0e6e6e`) — every land site in the network
 * has already claimed a road colour (Eagle's guide green, Euro's motorist blue,
 * Canada's maple red), so a *sixth* green-or-blue would read as "which one was
 * this again". Teal is the one hue in the shared palette that was reserved rather
 * than used — every other site's forecastnetwork.css carries it as an unclaimed
 * accent — and it is the correct one for water on first principles: it is the
 * colour bathymetric charts and marine forecast graphics already use for depth.
 *
 * The mark is a wave crest, not a route shield or a leaf — there is no national
 * road signage for the open ocean, so the pictogram draws the thing itself, the
 * same way Forecast Canada's maple leaf does rather than borrowing a highway
 * motif that would not mean anything out past the coast.
