Art style: Modern Flat Illustration.
A 'Step 5' icon in a clean, professional silver. The text 'Taxable Brokerage' is displayed. An ornate, silver key is shown inserted into a large, white modern door. The door is slightly ajar, revealing a bright, open landscape beyond. The palette is dominated by whites, silvers, and soft greens, conveying a sense of freedom and possibility.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "Modern Flat Illustration" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "Modern Flat Illustration". Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "Modern Flat Illustration" idiom, not in any other medium.
