/* ============================================================
   ShortList landing — the allergen tool, "Lab grid" look (design 2026-10-21 §5).
   Ported from concepts/landing-lab-grid/css/style.css (tool, label, list, .after, overlay).
   Family accents (--c1…--c6) mark categories only; verdict hues never appear here.
   Hint marks are yellow highlighter + ink, never red. Values from tokens.css.
