Frontend: CSS auf allgemeine Klassen verschlankt (82 Zeilen)

- ID-Selektoren (#account-info, #delete-form button) und verschachtelte
  Selektoren (.entry .meta, .interactions .vote) entfernt
- wiederverwendbare Klassen: .card, .muted, .row, .ghost
- globale a/h1/h2-Regeln, Farben als CSS-Variablen (--border, --danger)
- HTML/JS synchron umgestellt; counts-Span via querySelector("span")
- Cross-Check: keine toten CSS-Klassen, keine unbekannten Referenzen
