   THE LOCAL STOP
   Night-transit identity for a city-life journal.

   Shape system: cards and panels 16px, form inputs 10px,
   buttons and chips are full pills. No mixing.
   Theme: locked dark (the board after dusk).
   Accent: one signal yellow. Category colors are line colors,
   used as data encoding only (metro-line legend).
