/**
 * SG Attractions redemption terminal.
 *
 * A scanner-first counter UI layered on Bootstrap 5.3. Designed for handhelds
 * held at arm's length under bright light: large tap targets, high contrast,
 * unmistakable result states. Yellow and green come straight from the SG
 * Attractions logo; the logo's blue is deepened to a dark navy so large
 * surfaces (app bar, primary buttons) stay calm behind the yellow mark.
