 *
 * The identity is the game's, taken straight from app/ui/theme.js: a near-black
 * world where everything that matters emits light. Nothing here is an image —
 * the hero, the trail, the hazards and the icon are all CSS and inline SVG, for
 * the same reason the game has no sprites.
 *
 * Dark by default with a light theme via [data-theme="light"], following the
 * house one-pager pattern. Unlike the client sites, dark is not merely the
 * default here — it is what the product looks like, so the light theme is a
 * courtesy rather than a peer.
