/* ============================================================
   help.css · PTHelp — the in-app Help Center / user guide.
   Reuses the app's theme tokens (var(--bg), --ink, --accent…)
   from app.css so it tracks light / blueprint. Two-pane layout:
   a categorized topic sidebar + a scrollable article pane, with a
   client-side search box on top. Self-contained; no images — all
   visual aids are inline SVG/CSS "mockups" (.hc-mock*).
