/* Command-K overlay (Sprint v5-11.5 foundation)
 * -------------------------------------------------------------------------
 * Locked spec: docs/octopus/v5_11_5_sprint_brief.md §"Part 3 — Command-K"
 *
 * Self-contained overlay component. Drop the assets into any page via:
 *   <link rel="stylesheet" href="/assets/cmdk.css">
 *   <script defer src="/assets/cmdk.js"></script>
 *
 * No HTML markup required — the JS injects the overlay nodes on first
 * activation. Activation: Cmd-K (macOS) / Ctrl-K (Win/Linux) or click
 * any element with `data-cmdk-trigger`.
 *
 * Live-token mapping — uses both legacy team-pages dark tokens (--bg-0,
 * --fg-primary, --accent-primary) and the mockup-bridge tokens. Falls
 * through to hardcoded dark defaults when neither is defined.
