/* =====================================================================
   SENTARI DIGITAL — design system v4 ("Workbench Serif")
   A deliberate merge:
     - v2 "Blueprint Workbench" bones: dark technical surface, ONE disciplined
       signal-teal accent + rare warm cream, hairline blueprint grid, node/wire
       motifs (this product literally authors node graphs), monospace metadata.
     - v3 "Lumen" voice: Newsreader optical-serif display headings bring editorial
       warmth on top of the engineering grid — a restrained serif (clean `f`) in place
       of Fraunces' expressive (cringe) swash letterforms.
   Still deliberately NOT the generic AI look — no gradient soup, no glass blobs.
