/*
 * Phase 2 — User Guide styling. All chapter-body rules are scoped to
 * `.help-content` so the typography in `app/views/help/chapters/*.html`
 * doesn't leak into the rest of the dealer UI. The Phase 1 build runs
 * kramdown with `header_offset: 1`, so chapter `## N.N` headings render
 * as `<h3>`, `### N.N.N` as `<h4>`, and so on.
 *
 * The `.help-icon` rule at the bottom belongs to Phase 4 (per-page "?"
 * affordance) but the styling lives here so the help system's CSS sits
 * in one file.
