/* Vesica — the documentation page.
   The layout the reference uses for its long-form page: an 800px block centred
   in the viewport, split into a 150px sticky contents rail and a 630px content
   column. Inside the content column, every section runs headline-left /
   body-right above a full-width grid of cards.
   Sizes are in px because they were measured off screenshots. The type here is
   small on purpose — 10px eyebrows, 12.5px body — which is what the reference
   does and what makes the page read as documentation rather than marketing. */
