Description
We are looking for an elite Senior Front-End Engineer to build a clean, minimalist, high-status financial data terminal. Our Python/FastAPI backend is already fully completed, passes 55 integration tests, and is live-deployed on a public Railway cloud environment with strict PostgreSQL Row-Level Security (RLS) isolation walls. Your objective is purely to build the front-end viewport and hook it to our streaming API endpoints. THE REQUIREMENTS: 1. STYLISTIC BOUNDARY: This is an institutional Wall Street deal terminal, NOT a trendy tech startup app. There will be zero heavy gradients, zero curved card borders, and absolutely no dark-mode cyber aesthetics. 2. THE THEME: An immaculate, un-rounded, light-mode corporate ledger spreadsheet interface. - Base Canvas: #F8F9FA (Pristine paper white) - Primary Ink & Borders: #0A192F (Commanding corporate navy) - Accent Triggers: #D32F2F (Accounting crimson red) / #1B5E20 (Audit statement green) 3. THE ARCHITECTURE: The layout features a skeuomorphic "Manila Filing Folder" navigation system at the top-aligned header axis. Clicking different folder tabs must dynamically re-filter and re-render the tabular text rows below in active memory loops using fixed character-width fonts (like JetBrains Mono or SF Mono) so all numbers perfectly match on straight vertical grid scales. 4. THE TECH STACK: React, Tailwind CSS, Vite. Absolute component cleanliness and optimized API data fetching are mandatory. We bypass long behavioral interview loops. If
