   PORTFOLIO-CORE.CSS — Codex Studio v0.5
   ──────────────────────────────────────────────────────────────────────
   Стили, нужные для initial paint index.html (sidebar + work-card grid).
   Содержит: per-card .work-card[data-id="..."] backgrounds (v0.8.8a).

   ВАЖНО: подключать ПОСЛЕ shared.css. Опирается на токены из tokens.css
   и базовые стили work-card из shared.css.

   Split-out: вынесено из portfolio.css ради LCP — case-view стили
   ушли в portfolio-case.css и грузятся lazy при открытии кейса.

/* ═══════════════════════════════════════════════════════════════════════
   v0.8.8a — per-card thumb backgrounds (18 work-cards on index.html).
   Раньше каждая карточка имела inline style="background:linear-gradient(...)".
   Нарушало build-rule B2 (no inline styles). Переведено на атрибут-селектор
   по существующему data-id. Default fallback — .work-card__thumb { background: 
   var(--color-work-card-bg-hover) } в shared.css L929.
