HilfePage.tsx: accordion via <details>/<summary> (native, accessible, mobile-first);
9 sections in du-Form: Erste Schritte, Rennmaeuse, Becken, Wuerfe, Genetik,
Stammbaum, Abgabe-Ablauf, Statistik, Datensicherung. All UI labels imported from
de.ts (rename-safe); SCHECKE/Rex warnings verbatim from genetics.warnings.
de.ts: de.nav.help + de.hilfe (title, subtitle, 9 section keys)
AppShell.tsx: Hilfe (heart question mark) added to SECONDARY nav (Mehr-sheet on phone,
sidebar on desktop)
App.tsx: Route path=hilfe -> <HilfePage />
hilfe.css: accordion, hint boxes, warning colour; piggybacks on existing CSS vars
e2e/hilfe.spec.ts: 3 smoke tests x 2 viewports = 6 new tests
-- Hilfe reachable via nav
-- First accordion section expands on click
-- SCHECKE warning visible in Genetik section
Full evidence: dotnet test 18/18, npm test 47/47, npm run build ok,
npm run e2e 54/54 (48 existing + 6 new hilfe tests).
