   matter® — the design system

   Extracted verbatim from /home-v6/, which reproduces Matter's own Figma
   design (Matter Brain Dump — UI, node 994:19071). V6 is the locked system;
   this file is its single source of truth.

   Carries: fonts, tokens, reset, type scale, layout, controls, the floating
   pill nav with its mega-menu, and the footer. Prefix mtr-.

   Anything unique to one page lives in that page's own stylesheet, which
   loads after this one and keeps its own prefix.
