/* Hopper Reach — map-first design (operator-owned).
   Palette: bus red, blind black with LED amber, frog green; colour-blind-safe reach dots.
   Type: Archivo (condensed, signage) for display, Atkinson Hyperlegible Next for text, its Mono for times.
   Dark colours apply only on touch devices (phones, tablets); desktops always stay light. */
