/* Susdle legal-site styles — the apex chapbook.
   Tokens copied verbatim from packages/client/src/design/tokens.css
   (locked in DESIGN.md). Duplicated intentionally so the static apex site
   stays fully decoupled from the app build — no framework, no workspace import.
   Treatments (paper grain, wordmark, ornaments, village plate) are reproduced
   from the shipped app (global.css, Wordmark.css, ChapbookDivider.css,
   VillageIllustration.css) so the apex reads as the same printed world. */
