/* Lammark styles: mobile first, plain CSS.
   The idea: a transit line map. One red route line is the only repeating device:
   it shows up in the hero picture and as the three stops in "How it works".
   Everything else is flat, calm and signage-like.
   Shape rule: panels 16px, form fields 12px, buttons are pills. */
