Design doc only — no code touched. Recommends keeping /deadlines + /appointments
URLs but rendering one EventsPage component (smallest-diff Option A1), backed
by a new EventService that delegates to existing Deadline/AppointmentService
(Option B1). Two-rail bucket summary on Beides (5 deadline + 3 appointment),
detail pages stay separate, /agenda timeline left alone. §F lists 17 questions
gating m's greenlight, including a premise correction: the brief described
/agenda as the appointment list — actually it's a pre-existing cross-type
timeline; the appointment list is /appointments.
