/*
 * reference.css — styles for the /reference section (index + element pages).
 *
 * Scoped port of the Next site's globals.css rules that the reference pages
 * use (code windows, toks, nav, cards, tables, sem-md example) — every rule
 * lives under .ref-docs so the section styles itself without coupling to the
 * shell stylesheet (semtext-site.css). Palette values are the site's, retyped
 * verbatim: when the shell consolidates these, the .ref-docs block below is
 * the thing to delete.
 *
 * Hologram note: Hologram templates escape all text — classes carry meaning,
 * text nodes are inert. The island bridge (semtext-island.js) flips
 * figure.is-live to reveal the JS-only controls (view pills, copy/save),
 * which stay display:none server-side so the zero-JS page hides them —
 * the Next site's "pills appear only under JS" behaviour.
