/* ===========================================================================
 * sx-legal.css — Legal & Documents hub + shared reading layout (#3079)
 *
 * Scoped under `.sx` and built entirely on `--sx-*` design tokens, so light /
 * dark themes (the dark values live under `[data-theme="dark"] .sx`) come for
 * free. Covers: the doc header, the two-column reading shell (sticky cross-
 * document sidebar + per-page TOC | long-form prose), the prose typography
 * (headings, lists, links, tables, callouts), the mobile "On this page"
 * disclosure, and the `/legal` hub landing cards.
 * ======================================================================== */

/* ───────────────────────── Shared doc / hub header ───────────────────────── */
/* The full-viewport breakout — so the gradient + bottom border span the
 * viewport instead of stopping at the 1200px `.container` box (the original
 * "edges of the gradient") — comes from the shared `.legal-header` entry in
 * the `.sx-bleed` rule in sx-home.css (#3080). The inner `.sx-container`
 * keeps content centered. */
