Sprint 2 UI and brand refresh

Workbench: ramp-adjusted headline (TCO, net run-rate, NPV, IRR, payback),
financial model panel with internal-only investment, year-by-year cash flow,
scenario panel (presets + custom, presented scenario, report comparison),
overlap heat map, shelfware and expansion panel, editable implementation
timeline (drag, resize, row editor, dependencies, reset), version history
with compare and restore, deal status, customer logo.

Deliverables: report, Word and new PowerPoint deck present the chosen
scenario with net figures only; investment and dossier entitlements never
itemized (covered by the leak suite). Exports and printing snapshot
automatically.

New pages: Portfolio dashboard, Settings (company name, logo, accent).
Knowledge base: duplicate queue with merge, confidence and sourcing,
TCO defaults, needs-review filter.

Brand: VMware by Broadcom palette per Brand Guidelines.pdf; Darkmode navy
dark theme; AA-safe accent ink; business units remapped to palette.
