   PAIS · shared design system (v2)
   Dark editorial luxury — one theme for the marketing site AND the Control Room,
   so the two finally look like the same product.

   Principles: near-black layered surfaces · brass accent used sparingly ·
   Fraunces serif for display, Inter for body, JetBrains Mono for data labels ·
   tabular figures on every number · hairline borders + soft depth · subtle grain.
