                Salon system — design spec for Slices 2 + 3 (Complete dialog + Sales ledger report). Continues Casey's Slice 1 spec.
              
          
    Design Specification: Slices 2 & 3 — Complete-Treatment Dialog + Sales Ledger Report


Context. This continues the design started in Casey's Slice 1 gist. Slice 1 (backend payment capture + completion gate) shipped as PR #90 on feat/service-payment-capture. This document specifies the two remaining slices: the staff-facing 完成療程 dialog (Slice 2) and the redesigned /reports ledger page (Slice 3).
