/* ---- Ajutor și ghid (Help & Guide) -------------------------------------
   Port of the Client app's Help & Guide styles (client/frontend/css/
   modern_coreidon.css, "Help & Guide" block) onto the Rebut Hub palette.
   Rendered by HUB/views/viewHelp.js; content in HUB/help/helpContent.js.

   A documentation view, not a dashboard: a section strip, a contents rail and
   a list of collapsible topics. Card bodies are HTML authored in
   helpContent.js, so every rule under .help-body targets a bare tag — there
   are no classes in the content to keep in sync with this stylesheet.

   Breakpoints are CONTAINER queries on .help-page, not media queries: inside
   the HUB the 280px sidebar takes part of the viewport, so the page's own
   width — not the window's — decides whether the contents rail fits.
   Mobile-first: the base rules are the phone layout. */
