/* IATHEON · Field Journal skin (2026-11-10).
   A research notebook on warm parchment: ivory surfaces, editorial serif headings, hairline rules instead of shadows,
   and one clay accent kept for the single action a page asks for. Reference: the "Anthropic" entry on Refero Styles
   (styles.refero.design), read as a direction, not copied. Its greys are darkened where the RISCON readability
   guideline asks for 4.5:1 text contrast, and body text stays 16px / 1.6 with no negative tracking.
   Every rule is scoped to :root[data-skin="journal"]; the other skins are untouched. */
