   Library Occupancy — compact, graphic status cards
   AUX CDN handles global typography, colors, header/footer chrome,
   and the page-header. Everything below is specific to this
   experiment: the occupancy legend, card grid, and radial gauge.
   AUX has no progress/meter/gauge component today (checked Cards,
   Factoid Collections, Alert, Tables in the reference storybook),
   so the gauge itself is a custom, documented addition — see
   process.html for the full fidelity breakdown.
