   THE NEW WAVE — design system
   --------------------------------------------------------------------------
   Base is true black (#000): the product renders are shot on pure black, so
   the watch sits in the page with no visible edge. Accent colour only ever
   comes from the product — lume green after dark, strap colours in the
   configurator. The octagon of the case is the one recurring device: button
   corners, frames, the slider handle, the strap chips.
