   GoMart case study — summary-v2 theme + web components

   Visual system follows Raisin / OLX:
   - No decorative background images behind content. Content sits on paper,
     paper-dim, or a single flat client tint.
   - Layout is built from the shared .period-split primitives (50/50, 60/40).
   - Section rhythm comes from .section / .period / .period__head / .period__story.
