/*
 * SICK LiDAR Developer Guide: themed to match the sensor's own web UI
 * ==============================================================
 * Colours sampled directly from the device application (SICK Synergy
 * design system). The docs use a single light appearance (dark mode
 * has been removed); the brand blue and accents come from the device.
 *
 * Device palette (sampled live):
 *   #000206  page background      #00051a / #0e1633  surfaces / cards
 *   #262f55  borders              #4d5473  secondary       #777ea4  muted text
 *   #e9ebf1  body text            #005aff  primary blue    #3183fe  focus
 *   #5e97fc / #91bbff  light blue #a5e1b9  green (success)  #8a6000  warning
