/* ============================================================================
   Brand tokens — Innovation Forum × R1X.

   Every page on this origin links this file FIRST. It exists because the
   sign-in page and the workspace had drifted into two different products: one
   in system fonts, rounded corners and a neutral grey; the other in Barlow,
   square corners and the green ramp. A participant met the first, signed in,
   and was handed the second.

   Anything below is shared identity — fonts, palette, reset, the primitives
   that carry the brand. Page layout does NOT belong here; it belongs in the
   page's own stylesheet.
