Replace the last two holdouts: the dashboard partner-identity fallback now uses the real useMe().partner name, and the decorative MRR sparkline (dashboard + reports) moves to a generated useMrrTrendline() — deterministic, clearly placeholder-only, until a daily MRR-snapshot job exists. Removes the dead sparkLast/sparkTrendPct vars. The data/customers.ts fixture module is now fully deleted; the partner portal carries no mock business data.
Migrate the partner-mode customer switcher, in-customer banner, sidebar tile and the team invite/teammate panels off the data/customers fixture onto the real /api/partner/tenants list (shared key, gated to partner-staff so the global shell doesn't 403 for other users). Active customer resolves by tenant _id (the key the customers page already passes to partnerMode.enter); partner-identity labels now use the real partner name from useMe. Removes the now-unused customers + CustomerOrg-list fixture export and the dead setCustomer helper. Verified in UI: switcher + enter/exit show real Baslund Test / Baslund Research ApS.
Drop partnerTeam, partnerInvoices, partnerActivity and partnerAudit from data/customers.ts — these had no remaining importers now that team, billing, dashboard activity and audit run on real data. The still-used partner / customers / partnerMrrSparkline exports (partner-mode customer switcher + decorative sparkline) stay until those consumers are migrated.
Move partner domain types out of data/customers.ts into types/partner.ts so the fixture data exports can be removed later without breaking type imports. Add usePartnerTenants / usePartnerMrr composables wrapping the shared-key partner fetches.
