/* ============================================================================
   portal-legacy.css — bridge between portal.js (uses old class names)
   and Brand System v2 (Claude Design handoff, new class names).

   Created 2026-05-04 to fix /ru/news + other JS-hydrated pages where
   portal.js renders DOM with classes (.section, .section--white, .container-wide,
   .section__title, .category-pill, .reveal, .load-more) that the v2 CSS
   doesn't define — so the page rendered without any styling.

   This is a thin compatibility layer; do NOT add new rules here.
   Long-term: refactor portal.js to use new BEM classes directly.
