/* =========================================================================
   HFS Robotics — FTC team #21770
   One motif: the dorsal fin from the HFS shark logo. It frames every photo
   (one swept corner), shapes the buttons (one sharp corner), marks the lists,
   and rises at full scale in the hero, the sponsor section and the footer.
   Colours are the team's own: logo navy, white, and gold for the action.
