Create a single-page “Website Under Construction” layout for the company Beyond Coordination. Tone: calm, professional, structured, and confident — not salesy, not overpromising, not playful. Design must follow a mechanical–blueprint aesthetic. Deep inky navy (#0A0F19). Faint rose-gold mechanical blueprint lines inspired by HVAC diagrams and architectural drafting. Include a subtle geometric radial pattern (Mechanical Vega style), but keep it minimal and technical. No floral or organic motifs.
