   Prism Lab — IoT Prism Laboratory, University of Bologna.

   Brand metaphor: a research apparatus that takes a single beam (a question,
   a dataset, a problem) and refracts it into a spectrum of work. The site
   reflects that with one disciplined accent on tinted neutrals; the literal
   spectrum appears intentionally — once at the top of every page as a
   hairline rule, and once on the homepage hero as the prism illustration.
