   Lyra shared site styles
   Source of truth: Figma "Lyra Sites" (node 68:348)

   The Figma frame is 1728 wide with 248px gutters around 1232px of content.
   Those exact numbers are reproduced at the L breakpoint; M and S step the
   type and rhythm down. Everything tunable is a custom property at the top
   of each breakpoint block, so re-tuning a breakpoint means editing numbers
   in one place rather than hunting through rules.
