预算分配矩形树图

Design a modern treemap infographic showing a fictional company budget allocation for LUMEN BIO in fiscal year 2026. Use a light neutral background and a controlled palette of forest green, desaturated blue, amber, terracotta, lavender-gray, and charcoal outlines. The composition should be a clean rectangular treemap with strong visual grouping and crisp typography. Include a header with the in-image text "LUMEN BIO Budget Allocation" and "FY 2026". Major blocks should be labeled "R&D 38%", "Manufacturing 22%", "Clinical 14%", "Operations 10%", "Marketing 7%", "IT 5%", and "Legal 4%". Within some blocks, add smaller labels like "Prototypes", "Reagents", "QA", "Cloud", and "Field Trials". Include a compact side legend reading "Total Budget $84.0M". Ensure the chart has precise edges, balanced annotation density, clean hierarchy, and sharp text rendering suitable for a technical gallery prompt.
