/* VisionSentinel Command - "Cinema" layout, with the team's mobile-card skin (13 Nov, see the end of the file).
   Deep slate surfaces, sage accent, monospace micro-labels; the camera image is the largest thing
   on the page and the case file sits next to it. Fonts are the ones Windows already has (Segoe UI,
   Consolas): no downloads, works offline. */
