/* Acclaira article kit (aeo-toolchain/article-kit, 17 Oct 2026) - base mechanics for every client article page.
   Each site's own stylesheet SKINS this: it sets the tokens below on :root and overrides what its design needs, so
   the "On this page" list and the tables look native to that site. Never below 12px (design_gate type floor).
   Tokens: --ak-ink --ak-muted --ak-rule --ak-accent --ak-surface --ak-tint --ak-zebra --ak-radius --ak-top
