The dashboard uses bg-ink (near-black) — the request is to make the top bar gold (the --accent / bg-accent token). I can see the header is bg-ink. I'll switch it to bg-accent with text-ink for all text/icons so contrast is correct.

The top nav now uses bg-accent (the gold oklch(0.72 0.12 75) token) as a solid background across every page. All text, icons, and interactive elements have been switched from white-on-dark to text-ink on gold, with the active nav link inverting to bg-ink text-accent for clear selection contrast. The logo "C" badge and user avatar also invert to ink-background with gold text to maintain the two-tone brand feel.

I have full context. Now I'll add bulk-upload mock data to mock-data.ts, add bulk-upload Copilot responses to the drawer, then write the full page.

Good — the file ends at line 846. Now I'll append bulk-upload data and write the page simultaneously:

Now update the copilot drawer to include bulk-upload prompts and responses:

Now write the full bulk-upload page:

Now verify the page compiles and loads:

The /bulk-upload page returns 200. The Bulk Upload & Portfolio Valuation screen is fully built with:

• 5-step progress flow — Upload → Field Mapping → Validation → Processing → Results, each step gates the next with proper state transitions
• Step 1 (Upload) — drag-and-drop zone with parsing animation, template download, and feature callouts
• Step 2 (Field Mapping) — full table with dropdowns, required field validation, Auto Map and Reset controls
• Step 3 (Validation) — summary strip (25 total / 20 valid / 3 errors / 2 warnings), expandable error and warning lists with Fix Inline and Ignore Warning per-row actions
• Step 4 (Processing) — animated circular progress with live status messages and summary stats
• Step 5 (Results) — 7-card KPI strip that filters the table, 3-tab chart panel (Value Distribution / Confidence Pie / Route Bars), Route Optimisation panel with Apply Best Route, a fully sortable and filterable 25-row portfolio table, a slide-in drill-down drawer with full artwork detail and navigation to /valuation/[id] or /simulation, plus a Sample File modal, Export Report modal with 4 download formats, and toast feedback on every action
