What this skill does
Pages: Signup / Login Guides signup and login page structure, domain choice, modal vs dedicated page, discount integration, and SEO. Signup is the conversion endpoint from landing pages and pricing; when discounts apply at registration (e.g., student discount), signup is the P0 placement. Distinct from landing-page-generator (acquisition); newsletter-signup-generator (email capture only).
