/* =========================================
   OSTROV — landing and section layout

   Ported from the pre-WordPress main.css. Design tokens now live in
   theme.json and are aliased in tokens.css, which must load first.
   ========================================= */

/* =========================================
   Gutenberg spacing reset

   Core global styles put `margin-block-start: 24px` between sibling blocks.
   Every container below already spaces its children — through `gap`, or
   through margins the design sets deliberately — so the two rules stack and
   every card grows taller than the original layout.

   Scoped to the design components on purpose: inside post content (a case
   study, say) the core rhythm is exactly what an editor expects.
