/* ── Logo: the route sign ─────────────────────────────────────────────────
   A location banner in the spirit of the DS games: a framed plate with a
   small landscape inside (sky, hills, trees, drifting clouds), standing in
   tall grass with a few flowers. Art: brand/*.png, made by
   scripts/gen_brand_art.py on a 164 x 40 pixel canvas.
   --k is the pixel scale: 2 on desktop, 4/3 on phones, so every art pixel
   lands on whole screen pixels. Motion: a gust of wind rolls through the
   grass (16 frames, ~100ms each) and the clouds drift. The grass tapers off
   at both ends, so the sign has no hard rectangular edge. All motion stops
   for prefers-reduced-motion. */
