/* app.css — DCR Job Walk: tokens, layout and the shared components.
 *
 * Built for a phone held in one hand on a job site, often in bright sun:
 * big touch targets (48px), strong contrast, the DCR red for the main
 * action. Light by default (readable outdoors), dark when the phone is.
 * Feature styles live next to this file (camera.css, annotate.css, …);
 * they use these tokens and never redefine them.
