ui: Headings kleiner + Library als Archiv-Zwilling (Sidebar weg)

- section-title 2.6→1.9rem max, 800→700; single-header h1 3→2.2rem max, 800→700;
  single-summary 1.4→1.2rem. Ruhiger, redaktioneller, site-weit.
- Library raus aus der zweispaltigen Sonderform: Übersicht = .atlas (gruppiert,
  wie Archiv-Root), Eintrag = .single (wie Essay) mit Quellen + Fuss
  (Gruppe · weitere Einträge · bearbeiten). library-nav-Partial entfernt.
- Voll CI-konform: Archiv und Library teilen jetzt dasselbe Gerüst.
