/* ==========================================================================
   Morcegão FM — Effects: radii, borders, shadows, motion
   Low radii (posters + stickers feel crisp, not soft). Deep shadows on
   the dark stage. Amp-glow rings for focus/live. Snappy, slightly springy
   motion — nothing floaty.
