TYPOGRAPHY
An editorial high-contrast serif in the style of GT Sectra/Reckless Neue (built with Fraunces at opsz 144 as the production-safe substitute) carries the wordmark, headlines, and route names — warm, literary, slightly at odds with the rest of the system's precision, deliberately. A clean grotesk mono (JetBrains Mono in production) handles every functional layer — times, seat numbers, coordinates, fare data.
