TODO:
immediate:

• replace with proxy API url
• placeholders for when no bus data / no buses left today
• svc E placeholder (make it show "resumes later today")
• actually make it register if its term or holiday (in getServiceStatus (src/utils/mobility.ts))
• update bus schedule
• button to switch to opposite side stop
• directional arrows for one way svc
• optimize: use useCallback/useMemo
• auto-switch to BTC when needed (and vice versa)
• fix text font size for selected/focused stop

future:

• show KR / BG MRT timings too why not
• make it just use a normal polyline so its easier (?) to update when route changes
• locate nearby classrooms
