/**
 * Westphal Solutions — Markdown tool styles
 *
 * Visually matched to ws-html.css so the two site tools read as siblings:
 * the same top bar, sliding-thumb toggle, button chrome, and two-pane layout
 * with a hairline gutter. Behaviour is unchanged — this only styles the markup
 * produced by the [ws_markdown] shortcode and driven by ws-markdown.js.
 *
 * The shared shell here is intentionally identical to ws-html.css; when you're
 * ready, both can collapse into one ws-tools base file with these two as thin
 * skins on top.
