Corporate Brand Launch Poster Helios

A large-format corporate brand launch poster announcing a fictional renewable-energy firm called Helios. Vertical A1 layout with a strict twelve-column grid showing through faint cyan guides at the margins. A single hairline-thin circle ninety percent the width of the page sits slightly off-centre, filled with a soft sunrise gradient moving from deep navy at the base to warm apricot at the top. Inside the circle, set in a clean grotesque sans-serif, the headline reads "HELIOS" in 240pt uppercase letters, optical-kerned, charcoal black. Beneath, a smaller line reads "A new energy company. Launching 09.14.2026." in 18pt sentence case. The lower third holds a horizontal rule and four small information blocks labelled "Solar", "Wind", "Grid", "You" with two-line descriptions in 9pt. Background is a warm off-white paper tone with subtle long-fibre texture. Lighting is flat studio reproduction. Palette: navy 1C2A4A, apricot F3A26D, charcoal 1A1A1A, paper FAF6EE. No mockup frame, just the poster surface.
