Budget Allocation & ROI Projector for paid advertising. Takes a monthly ad budget and allocates it across platforms, campaigns, and funnel stages with platform-specific CPM/CPC/CPA estimates, 3 budget scenarios (Conservative/Balanced/Aggressive), break-even analysis, and scaling roadmaps from $1K to $10K/mo. Use when the user says "/ads budget", "allocate my ad budget", "ad budget plan", "ROI projection", "how should I split my ad spend", "media budget", "répartir mon budget pub", "plan de budget publicitaire", "projection ROI/ROAS", "combien dépenser en pub", "budget Meta/Google/LinkedIn". Single deterministic deliverable (one financial model) — NOT a multi-angle audit.
