/* ============================================================
   /product — design system v2.

   Measured against Legora, Harvey and Affinity (3 product pages
   each). What they do and v1 did not:

     · Separation is by GROUND, not by rule. Legora draws exactly
       one border on a whole page; v1 drew 114 hairline edges.
     · Neutrals are near-achromatic. Their off-whites sit at
       chroma 1-5; the old cream (#f5f2e8) was chroma 13 and read
       as beige.
     · Surfaces are FILLED, never outlined.
     · Few radii, applied consistently.

   Palette: stone + black, with a dark blue-grey accent. Texture
   is generated (SVG turbulence), so it costs nothing to ship.
