/* Forecast Waves — the explorer page's own chrome.
 *
 * Everything with a counterpart on the sibling sites is *not* here: the card, rule,
 * badge, seg, btn, timeline and wind-option components all come from
 * forecastwaves.css, which carries the same component vocabulary as
 * forecasteuro.css and forecasteagle.css do. This file is only the layout a map page
 * needs on top of that — the instrument cluster, the stage and its overlays, the
 * legend bar and the kilometre-marker facts strip.
 *
 * Forecast Euro keeps the equivalent block inline in `ecmwf.html`. It lives in its
 * own file here because two pages share it (the ocean explorer and the Great Lakes
 * one are the same instrument pointed at different water), and duplicating 200 lines
 * of layout across two documents is how the two drift apart.
