/* Docs.css — docs-surface polish scoped to v0.21.0 / roadmap item #32.
 *
 * This sheet owns ONLY the classes introduced by item #32 (the
 * transcript metadata header and the session-root sibling list). The
 * pre-existing docs classes (.docs-article, .docs-empty, .docs-error,
 * .docs-source-link, .philosophy-body, .muted) live in App.css and are
 * deliberately NOT touched here — redefining them would race the #31
 * App.css token sweep for the same selectors. Every value below reads
 * a token from tokens.css so the new surfaces sit on the same
 * spacing/type/color scale as the rest of the docs chrome.
 *
 * Imported from DocsSessionTranscript.jsx + DocsSessionIndex.jsx (the
 * two components that render these elements). CSS custom properties are
 * not import-order-sensitive at use time, so the import site doesn't
 * matter for correctness.

/* ── Transcript metadata header ─────────────────────────────────────
 * A compact card above the rendered transcript body: title, the
