   DESIGN SYSTEM — shared with studio-spreza

   This token vocabulary (color, type, space, motion) is the canonical Studio
   Spreza family design system. The sister site studio-spreza mirrors the same
   tokens; visual differences are content-driven, not stylistic. If a token name
   here changes, mirror it there to keep the family coherent.

   Layers: tokens → base → layout → components (override order).

   Layout: three-track grid (gutter | measure | gutter). `<main class="layout-main">`
   uses subgrid so children can span `layout-full` (viewport-wide) or `layout-prose`
   (center column). Fallback: classic max-width + full-bleed breakout for aurora.

   Typography: fluid type ramps via clamp(); mono for UI chrome, serif for display.

   Grid templates: `--grid-columns-*` define repeatable column patterns for lists.
